ext2: Fix ki_pos update for DIO buffered-io fallback case 



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:
fb5de435 ("ext2: Move direct-io to use iomap"). I have chosen fixes tag
based on which commit got landed later to upstream kernel.

Fixes: 182c25e9 ("filemap: update ki_pos in generic_perform_write")
