page-flags: define behavior of Xen-related flags on compound pages
PG_pinned and PG_savepinned are about page table's pages which are never compound. I'm not so sure about PG_foreign, but it seems we shouldn't see compound pages there too. Let's use PF_NO_COMPOUND for all of them. Signed-off-by: Kirill A.
