ethtool-netlink ignores dev->hw_features and may confuse the drivers by
asking them to enable features not in the hw_features bitmask. For
example:
1. ethtool -k eth0
tls-hw-tx-offload: off [fixed]
2. ethtool -K eth0 tls-hw-tx-offload on
tls-hw-tx-offload: on
3. ethtool -k eth0
tls-hw-tx-offload: on [fixed]
Fitler out dev->hw_features from req_wanted to fix it and to resemble
the legacy ethtool behavior.
Fixes: 0980bfcd69 ("ethtool: set netdev features with FEATURES_SET request")
