dquot: move dquot transfer responsibility into the filesystem
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 responsible for the transfer. Most filesystems already do this, only ufs and udf need the code added, and for jfs it needs to be enabled unconditionally instead of only when ACLs are enabled.
