net/i40e: revert VLAN filtering fix

This reverts commit 4761f57d58c6f52543738dbe299f846d62d75895.
Introducing VLAN table by adding VLAN adminq command will cause NIC's
throughput drop obviously. It's a hardware issue.
With this revert, VLAN filtering can only work when promiscuous mode
is disabled.
