Subject: [PATCH] udp: advertise ipv6 udp support for msghdr::ubuf_info

Mark udp ipv6 as supporting msghdr::ubuf_info. In the original commit SOCK_SUPPORT_ZC was supposed to be set by a udp_init_sock() call from udp6_init_sock(), but
d38afeec26ed4 ("tcp/udp: Call inet6_destroy_sock() in IPv6 ...") removed it and so ipv6 udp misses the flag.
