[PATCH] block: Set req quiet flag if bio is quiet

The current behavior is that if bio flagged as BIO_QUIETis submitted to request based block device then the request
that wraps this bio in a queue is not quiet. RQF_FLAG is not
set anywhere. Hence, if errors happen we can see error
messages (e.g. in print_req_error) even though bio is quiet.
This patch fixes that by setting the flag in blk_rq_bio_prep.
