TAKE - quota

[Nathan Scott <nathans@xxxxxxxxxxxxxxxxxxxxxxx>]

This fixes a panic found by qa on "fuzzy" which uses xfs as a
module... we weren't properly cleaning up xqm.  If you see the
following backtrace (can only happen if you're using xfs+quota
as a module), the problem is now fixed in the dev tree.

        - rework the way we initialize and tear down the quota-related
          kmem zones.  this fixes a problem with (multiple) use of xfs
          as a module, found by auto-qa.
