Jan Kara a107df383c bfq: Drop pointless unlock-lock pair
commit fc84e1f941b91221092da5b3102ec82da24c5673 upstream.

In bfq_insert_request() we unlock bfqd->lock only to call
trace_block_rq_insert() and then lock bfqd->lock again. This is really
pointless since tracing is disabled if we really care about performance
and even if the tracepoint is enabled, it is a quick call.
