net: aquantia: driver should correctly declare vlan_features bits

Browse Source 
[ Upstream commit 8c61ab7f11 ]

In particular, not reporting SG forced skbs to be linear for vlan
interfaces over atlantic NIC.

With this fix it is possible to enable SG feature on device and
therefore optimize performance.
