mm balloon: umount balloon_mnt when removing vb device
With CONFIG_BALLOON_COMPACTION=y the kernel will mount balloon_mnt for
balloon page migration when we probe a virtio_balloon device. However
we do not unmount it when removing the device. Fix this.
Fixes: b1123ea6d3b3 ("mm: balloon: use general non-lru movable page feature")
