[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.
