[PATCH] vlan: enable GRO if real_dev supports it

Currently vlan devices don't have GRO by default as none of the Ethernet
drivers add NETIF_F_GRO to their vlan_features.

As GRO is a software feature just propogate GRO from the real_dev in the
vlan core. There is no need to have the drivers each add NETIF_F_GRO to
their vlan_features.
