8.0 still allow creating ipv6 udp socket in jail without ipv6 ip

Hi!
After r188146 creating tcp ipv6 socket in jail without ipv6 ip is not
allowed, but udp socket is allowed.
I use this code to test:

#include <netinet/in.h>
#include <sys/socket.h>
#include <string.h>
#include <stdio.h>
#include <errno.h>

int main(int argc, char **argv)
{
	int	 sockfd;
	struct sockaddr_in servaddr;
	char sendline[] ="test";

	bzero(&servaddr, sizeof(servaddr));
	if( (sockfd = socket(AF_INET6, SOCK_DGRAM, 0))<0){
		fprintf(stderr, "socket(): %s\n", strerror(errno));
		return(1);
	}
	servaddr.sin_family = AF_INET;
	servaddr.sin_port = htons(12345);
	int r=inet_pton(AF_INET, "10.10.10.10", &servaddr.sin_addr);
	if(r<0){
		fprintf(stderr, "inet_pton(): %s\n", strerror(errno));
		return(1);
	}else if(r==0){
		fprintf(stderr, "call inet_pton() with incorrect address\n");
		return(1);
	}

	if( sendto(sockfd, sendline, strlen(sendline), 0, (struct sockaddr *) &servaddr, sizeof(servaddr)) < 0 ){
		fprintf(stderr, "socket(): %s\n", strerror(errno));
		return(1);
	}
	return(0);
}
