For various error conditions the bfa driver just returns 'DID_ERROR', which carries no information at all about the actual source of error. This patch updates the error handling to return a correct error code, depending on the type of error occurred.

Issue: Driver holds rom-lock for too long during reset recovery. During adapter reset testing, it was found that the driver holds the rom-lock for too long, because of which other drivers fail to acquire the rom-lock, leading to reset failures. The primary cause is, in the bootstrap code, while holding the rom-lock, the driver checks if the peg is halted, causing a 2 second contention. Fix: When a reset recovery starts, the driver deduces the cause, and sets appropriate flags in watchdog & recover_adapter routines. This flag should be used to determine if bootstrap is invoked from probe or reset context, reducing the rom-lock footprint of the drivers.

Issue: minidump data collection fails as driver reports data mismatch Fix: When the driver encounters a new entry type that it cannot process, it should just skip the entry and adjust the total buffer size by subtracting the skipped bytes from it. This is to ensure that there is no data mismatch because of the new entries.

Issue: Pending IO wait does not complete after triggering Graceful reset, causing ack timeout and call traces. Fix: 1. Reducing the IO command wait timeout before triggering reset, as logically also timeout should be less than reset timeout (10sec). 2. Moving the abort IO after chip reset, because only after chip reset, driver owns the IO otherwise it is with firmware and can still revert back with response.

In iSCSI Boot scenario, when machine is reboot/shutdown phase the active sessions are not closed. Driver queue cleanup is done as part of unload and device is disabled. Sessions are still active, iSCSI commands are issued from session which comes to driver, as driver cleanup and device disabled there is kernel stack dump with errors. Fix is invoking iscsi_session_failure with ISCSI_ERR_INVALID_HOST on all the active sessions when shutdown routine is called.
