[PATCH 03/17] BLOCK: Stop fallback_migrate_page() from using page_has_buffers() [try #2]

[David Howells <dhowells@redhat.com>]

From: David Howells <dhowells@redhat.com>

Stop fallback_migrate_page() from using page_has_buffers() since that might not
be available.  Use PagePrivate() instead since that's more general.
