fs: don't call ->writepage from __mpage_writepage

All callers of mpage_writepage use block_write_full_page as their
->writepage implementation when called from mpage_writepages
(although for ntfs3 this is obsfucated a bit).

Just call block_write_full_page directly instead of going through
the ->writepage indirection.
