Remove is_port guard
Remove is_port guard

Sockets in gen_tcp have always been ports, but assuming this is abusing
the interface since the type is documented as opaque. The assumption no
longer holds with the socket backend (eg. -kernel inet_backend socket),
so remove the is_port guard in the test functions
diameter_tcp:ports/0,1.
