ext2: Fix ki_pos update for DIO buffered-io fallback case
commit 8abc712ea4867a81c860853048f24e511bbc20f2 upstream.
Commit "filemap: update ki_pos in generic_perform_write", made updating
of ki_pos into common code in generic_perform_write() function.
This also causes generic/091 to fail.
This happened due to an in-flight collision with:
fb5de4358e1a ("ext2: Move direct-io to use iomap"). I have chosen fixes tag
based on which commit got landed later to upstream kernel.
Fixes: 182c25e9c157 ("filemap: update ki_pos in generic_perform_write")
