ocfs2: Gell into ocfs2_xa_set() 

ocfs2_xa_set() wraps the ocfs2_xa_prepare_entry()/ocfs2_xa_store_value()
logic.  Both callers can now use the same routine.  ocfs2_xa_remove()
moves directly into ocfs2_xa_set().

* Prepares loc->xl_entry to receive the new xattr. This includes

* This also includes deleting entries, but don't call this to remove
* a non-existant entry. That's just a bug.
*
* Note that this modifies the data. You did journal_access already,
* right?
