Yisheng Xie 9c57b5808c 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: b1123ea6d3 ("mm: balloon: use general non-lru movable page feature")
