If fast fail is enabled and we encounter a WWPN moving from one port id to another port id with I/O outstanding, if we use the move login MAD, although it will work, it will leave any outstanding I/O still outstanding to the old port id. Eventually, the SCSI command timers will fire and we will abort these commands, however, this is generally much longer than the fast fail timeout, which can lead to I/O operations being outstanding for a long time. This patch changes the behavior to avoid the move login if fast fail is enabled. Once terminate_rport_io cleans up the rport, then we force the target back through the delete process, which re-drives the implicit logout, then kicks us back into discovery where we will discover the WWPN at the new location and do a PLOGI to it.
