Hannes Reinecke 268940b80f scsi: scsi_dh_alua: Return BLK_STS_AGAIN for ALUA transitioning state
When the ALUA state indicates transitioning we should not retry the command
immediately, but rather complete the command with BLK_STS_AGAIN to signal
the completion handler that it might be retried.  This allows multipathing
to redirect the command to another path if possible, and avoid stalls
during lengthy transitioning times.
