NetLabel: Add IP address family information to the netlbl_skbuff_getattr() function

Browse Source 
In order to do any sort of IP header inspection of incoming packets we need to
know which address family, AF_INET/AF_INET6/etc., it belongs to and since the
sk_buff structure does not store this information we need to pass along the
address family separate from the packet itself.
