net/mlx5: HWS, Fix IP version decision

Browse source

Unify the check for IP version when creating a definer. A given matcher
is deemed to match on IPv6 if any of the higher order (>31) bits of
source or destination address mask are set.

A single packet cannot mix IP versions between source and destination
addresses, so it makes no sense that they would be decided on
independently.
