ext4: allow DAX writeback for hole punch
commit cca32b7eeb4ea24fa6596650e06279ad9130af98 upstream.
Currently when doing a DAX hole punch with ext4 we fail to do a writeback.
This is because the logic around filemap_write_and_wait_range() in
ext4_punch_hole() only looks for dirty page cache pages in the radix tree,
not for dirty DAX exceptional entries.
