scsi: smartpqi: revert propagate-the-multipath-failure-to-SML-quickly
Correct a rare multipath failure issue by reverting commit 94a68c814328 ("scsi: smartpqi: Quickly propagate path failures to SCSI midlayer") [1]. Reason for revert: The patch propagated the path failure to SML quickly when one of the path fails during IO and AIO path gets disabled for a multipath device. But it created a new issue: when creating a volume on an encryption-enabled controller, the firmware reports the AIO path is disabled, which cause the driver to report a path failure to SML for a multipath device. There will be a new fix to handle "Illegal request" and "Invalid field in parameter list" on RAID path when the AIO path is disabled on a multipath device.
