Previous implementation would disconnect _all_ clients when running `ACL
LOAD`, which wasn't very useful.
This change brings the behavior in line with that of `ACL SETUSER`, `ACL
DELUSER`, in that only clients whose user is deleted or clients
subscribed to channels which they no longer have access to will be
disconnected.
