sock_diag: Fix module netlink aliases

Browse Source 
I've made a mistake when fixing the sock_/inet_diag aliases :(

1. The sock_diag layer should request the family-based alias,
   not just the IPPROTO_IP one;
2. The inet_diag layer should request for AF_INET+protocol alias,
   not just the protocol one.

Thus fix this.
