[SCSI] tgt: fix warning
Using scsi_tgt_lib in a new target module, we were getting the following warning and a stack traceback on every I/O completion: WARNING: at block/blk-core.c:1108 Which is claiming we may be leaking a bio. We don't leak bios (blk_rq_unmap_user should free them). Set rq->bio to NULL before calling scsi_host_put_command(). This was as advised by Fujita Tomonori.
