[GFS2] Use vmalloc() in dir code
When allocating memory to sort directory entries, use vmalloc() rather than kmalloc() since for larger directories, the required size can easily be graeter than the 128k maximum of kmalloc(). Also adding the first steps towards getting the AOP_TRUNCATED_PAGE return code get in the glock code by flagging all places where we request a glock and we are holding a page lock.
