This patch adds process_virtio_blk_request() that will be called
by virtio_blk transports to process incoming requests.
Meanwhile vhost_user_blk_request_finish() will be replaced with
a callback to the virtio_blk transport to notify of the result.
blk_request_finish() should only be called as direct result of
process_virtio_blk_request(), usually from it.
Some error paths now call vhost_user_blk_request_finish() directly,
if vhost_user_process_blk_request() was not called yet.
