net/mlx5e: Add ndo_set_feature for uplink representor 



After we have a dedicated uplink representor, the new netdev ops
doesn't support ndo_set_feature. Because of that, we can't change
some features, eg. rxvlan. Now add it back.

In this patch, I also do a cleanup for the features flag handling,
eg. remove duplicate NETIF_F_HW_TC flag setting.
