bareudp: use ipv6_mod_enabled to check if IPv6 enabled
bareudp_create_sock() use AF_INET6 by default if IPv6 CONFIG enabled.
But if user start kernel with ipv6.disable=1, the bareudp sock will
created failed, which cause the interface open failed even with ethertype
ip. e.g.
# ip link add bareudp1 type bareudp dstport 2 ethertype ip
# ip link set bareudp1 up
RTNETLINK answers: Address family not supported by protocol
Fix it by using ipv6_mod_enabled() to check if IPv6 enabled. There is
no need to check IS_ENABLED(CONFIG_IPV6) as ipv6_mod_enabled() will
return false when CONFIG_IPV6 no enabled in include/linux/ipv6.h.
