When a flaky disk is there in a topology then during driver load, discovery related I/O times out; which results in SCSI error recovery initiating host reset and then the controller won't see any disk. In this patch, The driver would return FAILED status to the host reset initiated due to discovery related I/O timeout if ioc->is_driver_loading is set. This flag would be set until we exit out of scsih_scan_finished(). i.e. During device discovery if one of the disk is flaky (which responds to some discovery commands and doesn't respond to some) the driver wouldn't perform host reset for discovery related I/O timeout. Instead it would return Failure for the host reset resulting in the flaky disk getting removed by the SCSI Mid layer, so other disks would be added correctly.
