net/ipv6: check for mistakenly passed in non-AF_INET6 sockaddrs
Same check as for IPv4, also do for IPv6. (If you passed in a IPv4 sockaddr_in here, the sizeof check in the line before would have triggered already though.) Signed-off-by: Marcus Meissner <meissner@suse.de> Cc: Reinhard Max <max@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
