Ah, you are right. After reading the code again this patch is not needed
anymore because xfs_file_iomap_begin() returns IOMAP_F_NEW whenever we
allocated block regardless whether it was zeroed-out or not. But if I get it
right, all the IS_DAX checks in __xfs_get_blocks() can be dropped now, cannot
they?
