Properly set ReceivePacketInformation socket option for dual-stack
On Windows if IPV6_V6ONLY == 0, we need to set both IPV6_PKTINFO and
IP_PKTINFO options in order to correctly receive the information from
IPv4 packets.
Instead of explicitly checking the IPv6_V6ONLY option via getsockopt,
this patch simply tries to unconditionally set the IPv4 option, and
ignores the potential error if the protocol is not IPv4-only.
Unix implementation is not touched by this patch, because there
enabling packet info for IPv6 also enables it for IPv4.
Also, an attempt to set IP_PKTINFO for AF_INET6 socket fails there
even if IPV6_V6ONLY == 0.
