[Intel-wired-lan] [PATCH net v1] iavf: Fix VF driver counting VLAN 0 filters

[Kamil Maziarz]

From: Michal Jaron <michalx.jaron at intel.com>

VF driver mistakenly counts VLAN 0 filters, when no PF driver
counts them.
Do not count VLAN 0 filters, when VLAN_V2 is engaged.
Counting those filters in, will affect filters size by -1, when
sending batched VLAN addition message.

Fixes: 968996c070ef ("iavf: Fix VLAN_V2 addition/rejection")
