iavf: Fix VLAN_V2 addition/rejection
Fix VLAN addition, so that PF driver does not reject whole VLAN batch.
Add VLAN reject handling, so rejected VLANs, won't litter VLAN filter
list. Fix handling of active_(c/s)vlans, so it will be possible to
re-add VLAN filters for user.
Without this patch, after changing trust to off, with VLAN filters
saturated, no VLAN is added, due to PF rejecting addition.
Fixes: 92fc50859872 ("iavf: Restrict maximum VLAN filters for VIRTCHNL_VF_OFFLOAD_VLAN_V2")
