net: aquantia: driver should correctly declare vlan_features bits

BugLink: http://bugs.launchpad.net/bugs/1794889
[ Upstream commit 8c61ab7f111a2b29d051348b9cb9a39804ebf1f8 ]

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.
