mm: call filemap_fdatawrite_range_kick() after IOCB_DONTCACHE issue

Browse source

When a buffered write submitted with IOCB_DONTCACHE has been successfully
submitted, call filemap_fdatawrite_range_kick() to kick off the IO.  File
systems call generic_write_sync() for any successful buffered write
submission, hence add the logic here rather than needing to modify the
file system.
