[PATCH 3/6] blk-flush: use blk_mq_request_bypass_insert()

[Ming Lei <ming.lei@redhat.com>]

In the following patch, we will use RQF_FLUSH_SEQ
to decide:

- if the flag isn't set, the flush rq need to be inserted
via blk_insert_flush()
- otherwise, the flush rq need to be dispatched directly
since it is in flush machinery now.

So we use blk_mq_request_bypass_insert() for requsts
of bypassing flush machinery, like what the legacy did.
