Fix gnttab_release_mappings -- it doesn't need to drop
page refcnts for host mappings as they are already
destroyed by put_page_from_l1e(). Also call
gnttab_release_mappings later (after destroying
page-table references) and from common code rather than
arch/x86.
Also a few other misc gnttab cleanups.
