devpts: plug the memory leak in kill_sb
When devpts is unmounted, there may be a no-longer-used IDR tree hanging off the superblock we are about to kill. This needs to be cleaned up before destroying the SB. The leak is usually not a big deal because unmounting devpts is typically done when shutting down the whole machine. However, shutting down an LXC container instead of a physical machine exposes the problem (the garbage is detectable with kmemleak).
