[PATCH] fix WARN_ON on XFS module unload

From: Christoph Hellwig <hch@lst.de>

This one is a little funny.  The SGI trees don't show this issue because dmapi
and quota are separate modules so they must be unloaded before xfs_fs_exit can
be called at all.

So let's move the exitcalls for them in mainline first to simulate that
behaviour.
