dsched_fq - Refactor and clean; handle flushes
* Factor out an fq_drain which will either cancel or dispatch all the
bios we have currently in all our fqp queues.
* Clean out old comments and code.
* Deal with flushes by not queuing them but rather letting dsched handle
them. By returning EINVAL, dsched_queue will dispatch the flush
itself.
