umem: fix up unplugging
commit 32587371ad3db2f9d335de10dbd8cffd4fff5669 upstream.
Fix a regression introduced by 7eaceaccab5f40 ("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.
