inet: collapse ipv4/v6 rcv_saddr_equal functions into one
We pass these per-protocol equal functions around in various places, but we can just have one function that checks the sk->sk_family and then do the right comparison function. I've also changed the ipv4 version to not cast to inet_sock since it is unneeded. Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: David S. Miller <davem@davemloft.net>
