net: stmmac: propagate feature flags to vlan 



stmmac_dev_probe doesn't propagate feature flags to VLANs.  So features
like offloading don't correspond with the general features and it's not
possible to manipulate features via ethtool -K to affect VLANs.

Propagate feature flags to vlan features.  Drop TSO feature because
it does not work on VLANs yet.
