igb: enable VLAN stripping for VMs with i350
For i350 VLAN stripping for VMs is not enabled in the VMOLR register but in the DVMOLR register. Making the changes accordingly. It's not necessary to unset the E1000_VMOLR_STRVLAN bit on i350 as the hardware will simply ignore it. Without this change if a VLAN is configured for a VF assigned to a guest via (i.e.) ip link set p1p1 vf 0 vlan 10 the VLAN tag will not be stripped from packets going into the VM. Which they should be because the VM itself is not aware of the VLAN at all.
