When a reconnect failed but re-login succeeded, __scsi_add_device was called again. In those cases, __scsi_add_device succeeded and returned the pointer to the existing scsi_device. fw-sbp2 then continued orderly, except that it missed to call sbp2_cancel_orbs. SCSI core would call fw-sbp2's eh_abort_handler eventually if there had been an outstanding command. This patch avoids the needless lookups and temporary allocations in SCSI core and I/O stall and timeout until eh_abort_handler hits. Also, __scsi_add_device tolerating calls for devices which already exist is undocumented behavior on which we shouldn't rely.
