Subject: 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
f5ff8422bbdd59f8c1f699df248e1b7a11073027 (Fix warnings with
!CONFIG_BLOCK).
