The current behavior for SCSI commands submitted while error recovery is ongoing is to retry command submission after error recovery has finished. See also the scsi_host_in_recovery() check in scsi_host_queue_ready(). Add support for failing SCSI commands while host recovery is in progress. This functionality will be used to fix a deadlock in the UFS driver.
