Subject: ice: Only disable VLAN pruning for the VF when all VLANs are removed
Patch-mainline: v5.4-rc1
Git-commit: cd186e51513c6b9cfdfa7280acf37db7e3dd114b
References: jsc#SLE-7926
Currently if the VF adds a VLAN, VLAN pruning will be enabled for that VSI.
Also, when a VLAN gets deleted it will disable VLAN pruning even if other
VLAN(s) exists for the VF. Fix this by only disabling VLAN pruning on the
VF VSI when removing the last VF (i.e. vf->num_vlan == 0).
