inet: ping: check sock_net() in ping_get_port() and ping_lookup()
We need to check socket netns before considering them in ping_get_port().
Otherwise, one malicious netns could 'consume' all ports.
Add corresponding check in ping_lookup().
Fixes: c319b4d76b9e ("net: ipv4: add IPPROTO_ICMP socket kind")
