The link information exists only on the leading hwfn,
but some of its derivatives [e.g., min/max rate] need to
be configured for each hwfn.
When re-basing the VF link view, use the leading hwfn
information as basis for all existing hwfns to allow
said configurations to stick.

The PF<->VF interface allows for the VF to request
multiple queues closure via a single message, but this has
never been used by any official driver.

We now deprecate this option, forcing each queue close
to arrive via a different command; This would be required
for future TLVs that are going to extend the queue TLVs with
additional information on a per-queue basis.

PF needs to validate the status of VF queues before asking firmware
to configure anything for them, but that validation is done in various
different forms - sometimes inadequate.

Add auxillary functions that can be used for testing of the queue
state and convert the various flows to use those instead of current
existing flows; Also, add missing validations where needed.

When starting the VF's vport, the PF would first configure
the status blocks of the VF and then reset them.
That would cause some of the configured information to be lost -
specifically it would mean that all the VFs queues would use
the Rx coalescing state-machine of the status block.

When PF responds to the VF requests it also cleans the HW-channel
indication in firmware to allow further VF messages to arrive,
but the order currently applied is wrong -
The PF is copying by DMAE the response the VF is polling on for
completion, and only afterwards sets the HW-channel to ready state.

This creates a race condition where the VF would be able to send
an additional message to the PF before the channel would get ready
again, causing the firmware to consider the VF as malicious.

When a VF is considered malicious, driver handling of the VF
FLR flow would clean said indication - but not if the FLR is
part of an sriov-disable flow.
That leads to further issues, as PF wouldn't re-enable the
previously malicious VF when sriov is re-enabled.

No reason for that - simply clean malicious indications in
the sriov-disable flow as well.

Change to support host<->firmware command return value.
Fix for vf mac addr state command.
1. Added support for firmware commands to return a value:
   - previously, the returned code overlapped with host codes, thus
     commands were only returning 0 (success) or -1 (interpreted as
     timeout)
   - per 'response_manager.h', the error codes are split into two fields
     (major/minor) now, firmware commands are grouped into their own
     'major' group, separate from the host's 'major' group, which allow f/w
     commands to return any 16-bit value
2. The command to set vf mac addr was logging a success message even if
   command failed.  Now command uses a callback function to log the status
   message.
3. The command to set vf mac addr was not logging a message when set via
   the host 'ip' command.  Now, the callback function will log an
   appropriate message.

When closing the ibmvnic device we need to release the resources used
