  datapath-windows: use ip proto for tunnel port lookup

In Actions.c, based on the IP Protocol type and L4 port of
the outer packet, we lookup the tunnel port. The function
that made this happen took the tunnel type as an argument.
Semantically, is is better to pass the IP protocol type and
let the lookup code map IP protocol type to tunnel type.

In the vport add code, we make sure that we block tunnel
port addition if there's already a tunnel port that uses
the same IP protocol type and L4 port number.
