scsi: smartpqi: Quickly propagate path failures to SCSI midlayer
Return DID_NO_CONNECT when a path failure is detected.
When a path fails during I/O and AIO path gets disabled for a multipath
device, the I/O was retried in the RAID path slowing down path fail
detection. Returning DID_NO_CONNECT allows multipath to switch paths more
quickly.
