The comment about the page always being locked is wrong, so copy
the locking protection from __set_page_dirty_buffers().  That
means moving the call to nilfs_set_file_dirty() down the
function so as to not acquire a new dependency between the
mapping->private_lock and the ns_inode_lock.  That might be a
harmless dependency to add, but it's not necessary.
