net: avoid initial "Features changed" message

Avoid "Features changed" message and ndo_set_features call on device
registration caused by automatic enabling of GSO and GRO. Driver should
have enabled hardware offloads it set in features, so the ndo_set_features()
is not needed at registration time.
