mount-encrypted: issue sync()s between umount stages

In an effort to reduce the chances of a kernel bug wrecking filesystems
during encrypted-stateful shutdown, add explicit sync() calls during
shutdown.

TEST=link build, shutdown with simulated panic in LOOP_CLR_FD results in
 successful journal replays
BRANCH=None
