acl: remove authz == nil checks 

These case are already impossible conditions, because most of these functions already start
with a check for ACLs being disabled. So the code path being removed could never be reached.

The one other case (ConnectAuthorized) was already changed in a previous commit. This commit
removes an impossible branch because authz == nil can never be true.
