Stefan Richter 0fa6dfdb0a firewire: fw-sbp2: don't add scsi_device twice
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.
