Tao Guo 665bcdee82 umem: fix up unplugging ...

commit 32587371ad upstream.

Fix a regression introduced by 7eaceaccab ("block: remove per-queue
plugging").  In that patch, Jens removed the whole mm_unplug_device()
function, which used to be the trigger to make umem start to work.

We need to implement unplugging to make umem start to work, or I/O will
never be triggered.
