[PATCH] uml: add per-device queues and locks to ubd driver

Replace global queue and lock with per-device queues and locks.  Mostly a
straightforward replacement of ubd_io_lock with dev->lock and ubd_queue with
dev->queue.

Complications -
There was no way to get a request struct (and queue) from the
structure sent to the io_thread, so a pointer to the request was
added.  This is needed in ubd_handler in order to kick do_ubd_request
to process another request.
Queue initialization is moved from ubd_init to ubd_add.
