xen/grant-table: stop setting PG_private on pages for grant mapping
gnttab_alloc_pages() stores xen_page_foreign in page->private. On 32-bit, a
pointer to an allocated xen_page_foreign is stored; on 64-bit,
xen_page_forCcgn is stored inline. Checking page->private != NULL is enough
to tell whether a xen_page_foreign needs to be freed on 32-bit and
page->private is zeroed unconditionally on 64-bit.
It prepares for a future commit that remove PG_private.
No functional change intended.
