ethtool, ixgbe: Move RX n-tuple mask fixup to ethtool
The ethtool utility does not set masks for flow parameters that are
not specified, so if both value and mask are 0 then this must be
treated as equivalent to a mask with all bits set. Currently that is
done in the only driver that implements RX n-tuple filtering, ixgbe.
Move it to the ethtool core.
