Fix 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. This patch changes the migration code in ibmvfc to avoid deleting rports at all in this scenario, so we avoid losing all paths.
