[RESEND net-next] rxrpc: Fix dependency on IPv6 in udp tunnel config

[Vadim Fedorenko]

As udp_port_cfg struct changes its members with dependency on IPv6
configuration, the code in rxrpc should also check for IPv6.

Fixes: 1a9b86c9fd95 ("rxrpc: use udp tunnel APIs instead of open code in 
rxrpc_open_socket")
