bsg: setting rq->bio to NULL
Due to commit 1cd96c242a829d52f7a5ae98f554ca9775429685 ("block: WARN in __blk_put_request() for potential bio leak"), BSG SMP requests get the false warnings: WARNING: at block/blk-core.c:1068 __blk_put_request+0x52/0xc0() This sets rq->bio to NULL to avoid that false warnings.
