I think just passing the hw_ctx is fine.  But I don't want drivers to
have to implement both methods, so we should make sure the new method
works for both the blk-mq and !blk-mq case.  Note that once thing the
new method should get is a bool last paramter similar to the one I
added to the queue_rq method in the block tree tree.

It might be worth it to simply do a global search and replace and pass
a hw_ctx method to all instances, too.
