Fix sending and receiveing protected managment frames.
Lack of protected flag for received protected action frames
causes report these frames as unprotected robust action frames.
If the driver in AP mode sent frame with protected flag and
CCMP header using IEEE80211_KEY_FLAG_SW_MGMT_TX flag,
the FW encrypted frames once again. From user side all
received SA Query Requests and Responses were skipped and
all protected action frames were sent as malformed packets.

On ARM-based (MSM mach), the pci_assign_resource() is passing
some invalid pointers and leading to L2 cache errors,
what prevents the PCI communication completly.

So far I have not found this funtion to be directly called by
any other wifi driver and did not found this assigning needed
on any other platform. So removing it completely.

Apparently firmware can sometimes report a
sequence with the first rx descriptor saying it's
not the last MSDU. In that case msdu_chaining
value could be overwritten saying it's not a
chained MSDU. This in turn led to skb_push panic
as the frame could be treated as an A-MSDU instead
of a chained MSDU.

msdu_payId was read before txrx tasklet was killed
so it was possible to end up using an invalid
sk_buff pointer leading to a panic.

Make sure to sanitize rx ring sk_buff pointers and
make the clean up go through all possible entries
and not rely on coherent-DMA mapped u32 index
which could be (in theory) corrupted by the device
as well.

this is not always efficient for all bus layer. For example SDIO
has an internal queue and worker making the queueing of FWS
unnecessary. Make it possible to bypass the worker if fws mode
is none using a bus interface configuration. For USB bus layer
this configuration is set true to have fws provide queueing
regardless the fws mode.

When a BSS provides both 2.4GHz and 5GHz bands, in many cases it
makes sense to choose 5GHz. Typically a 5GHz channel is less crowded
and has less interference and therefore its performance will be
better than a crowded 2.4 GHz channel. This patch configures
'join_pref' to induce firmware to preferably select 5GHz BSS.
