[ Upstream commit 9841d58f3550d11c6181424427e8ad8c9c80f1b6 ]

If a feature flag is only present in features, but not in hw_features,
the user can't reset it. Although hw_features may contain NETIF_F_HW_TC
by the point where the driver checks whether HTB offload is supported,
this flag is controlled by another condition that may not hold. Set it
explicitly to make sure the user can disable it.
