Fix a build error when BLOCK=n

mm/filemap.c: In function '__filemap_fdatawrite_range': mm/filemap.c:200: error: implicit declaration of function 'mapping_cap_writeback_dirty' This happens when we don't use/have any block devices and a NFS root filesystem is used. mapping_cap_writeback_dirty() is defined in linux/backing-dev.h which used to be provided in mm/filemap.c by linux/blkdev.h until commit f5ff842 (Fix warnings with !CONFIG_BLOCK).
