ixgbevf: fix null pointer dereference due to filter being set for VLAN 0
This change corrects an issue that resulted in a null pointer dereference for the addition of VLAN 0 without any VLANs being registered. Also this code removes some unnecessary checks for defines and the unnecessary setting of VLAN flags since that is now handled within the kernel via the vlan_features.
