Currently notify_change calls vfs_dq_transfer directly. This means
we tie the quota code into the VFS. Get rid of that and make the
filesystem responsibly for the transfer. Most filesystems already
do this, only ufs needs the code added, and for jfs it needs to be
enabled unconditionally instead of only when ACLs are enabled.
