ext4: fix a BUG_ON crash by checking that page has buffers attached to it
(cherry picked from commit 1f94533d9cd75f6d2826018d54a971b9cc085992)
In ext4_num_dirty_pages() we were calling page_buffers() before
checking to see if the page actually had pages attached to it; this
would cause a BUG check crash in the inline function page_buffers().
Thanks to Markus Trippelsdorf for reporting this bug.
