Jens Axboe b2c5d16b72 blk-mq: use plug for devices that implement ->commits_rqs() ...

If we have that hook, we know the driver handles bd->last == true in
a smart fashion. If it does, even for multiple hardware queues, it's
a good idea to flush batches of requests to the device, if we have
batches of requests from the submitter.
