This patch fixes an issue reported when performing a live
migration when multipath is configured with a short fast
fail timeout of 5 seconds and also to have no_path_retry
set to fail. In this scenario, all paths would go into the
devloss state while the ibmvfc driver went through discovery
to log back in. On a loaded system, the discovery might
take longer than 5 seconds, which was resulting in all paths
being marked failed, which then resulted in a read only filesystem.

Applied to 6.1/scsi-fixes, thanks!
