qeth: omit upstream checksumming for HiperSockets
For HiperSocket devices receive-path checksumming is not required.
Thus NO_CHECKSUMMING is used as default for HiperSocket interfaces.
For layer3 devices configured with NO_CHECKSUMMING received skbs
should have set their ip_summed field to CHECKSUM_UNNECESSARY.
