xfs: sanitize qh_lock wrappers
Get rid of various obsfucating wrappers for accessing the quota hash lock, we only keep the accessors for accessing the mplist and freelist locks as they encode a multi-level datastructure walk. But make sure all of them are defined in the same way as simple macros. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <david@fromorbit.com>
