netfilter: conntrack: fix bogus port values for other l4 protocols

We must only extract l4 proto information if we can track the layer 4
protocol.

Before removal of pkt_to_tuple callback, the code to extract port
information was only reached for TCP/UDP/LITE/DCCP/SCTP.

The other protocols were handled by the indirect call, and the
'generic' tracker took care of other protocols that have no notion
of 'ports'.

After removal of the callback we must be more strict here and only
init port numbers for those protocols that have ports.
