xen/gntalloc: release grant references on page free
gnttab_end_foreign_access_ref does not return the grant reference it is passed to the free list; gnttab_free_grant_reference needs to be explicitly called. While gnttab_end_foreign_access provides a wrapper for this, it is unsuitable because it does not return errors.
