In preparation for adding support for the lazytime mount option, we
need to be able to separate out the update_time() and write_time()
inode operations.  Currently, only btrfs and xfs uses update_time().

We needed to preserve update_time() because btrfs wants to have a
special btrfs_root_readonly() check; otherwise we could drop the
update_time() inode operation entirely.
