[PATCH] Use request_list as indicator that req originated from ll_rw_blk

From: Mike Christie <michaelc@cs.wisc.edu>,

It's cleaner and more correct to look at req->rl to determine whether this
request got from the block layer requests lists instead of using req->q.
It's handy to always have req->q available, to lookup the queue from the
request.
