[UDP6]: Restore sk_filter optimisation



This reverts the changeset

    [IPV6]: UDPv6 checksum.

    We always need to check UDPv6 checksum because it is mandatory.

The sk_filter optimisation has nothing to do whether we verify the
checksum.  It simply postpones it to the point when the user calls
recv or poll.
