scsi: core: Return BLK_STS_AGAIN for ALUA transitioning
Whenever we encounter a sense code of ALUA transitioning in
scsi_io_completion() it means that the SCSI midlayer ran out of retries
trying to wait for ALUA transitioning. In these cases we should be passing
up the error, but signalling that the I/O might be retried, preferably on
another path. So return BLK_STS_AGAIN in these cases.
[mkp: typo + fallthrough]
