Subject: iavf: Fix VF driver counting VLAN 0 filters
Patch-mainline: v6.1-rc5
Git-commit: 0e710a3ffd0caaf23b8791b041e8792f252f8e4f
References: jsc#PED-835

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")
