ixgbe: Set the correct pool when VLANs are added in SR-IOV mode. 

When VFs are allocated (as indicated by adapter->num_vfs is non-zero) then
the PF pool is no longer zero.  Instead it will be the same as the number
of VFs allocated.  When setting the VLVF entry for the PF we need to use
the correct pool otherwise the PF will get VLAN packets from the wire
because the packet will pass VFTA filtering and the PF has the default
pool, but it will not get VLAN packets from the VFs because it has
not set the correct pool bit in the VLVF entry.
