virtio_ballon: change stub of release_pages_by_pfn
and rename it to release_pages_balloon. The function originally takes arrays of pfns and now it takes pointer to struct virtio_ballon. This change is necessary to conditionally call adjust_managed_page_count in the next patch. Signed-off-by: Denis V. Lunev <den@openvz.org> CC: Michael S.
