Deny "pipex no" tunnel setting for pppx(4) interfaces. They are useless
with disabled pipex(4), because in such case npppd(8) successfully
establishes connection, but doesn't create corresponding interface, so
the traffic doesn't flow.
This is not applicable for pppac(4) interfaces, they work with disabled
pipex(4).
