nilfs2: change return type of nilfs_commit_chunk
change return type of nilfs_commit_chunk() as void from int, for nilfs_set_file_dirty() usually does not return error. This is an intermediate patch to reduce mark_inode_dirty() in nilfs_commit_chunk(). Signed-off-by: Jiro SEKIBA <jir@unicus.jp> Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
