[PATCH] Fix SCSI scanning slab corruption



There is a double free in the scsi scan code if a LLDD's slave_alloc()
call fails.  There is a direct call to scsi_free_queue and then the
following put_device calls the release function, which also frees the
queue.

Remove the redundant scsi_free_queue.
