Christoph Hellwig a05931ceb0 xfs: remove the global xfs_Gqm structure
If we initialize the slab caches for the quota code when XFS is loaded there
is no need for a global and reference counted quota manager structure.  Drop
all this overhead and also fix the error handling during quota initialization.
