Don't leak VLANClientState on PCI hot remove
destroy_nic() requires that NICInfo::private by a PCIDevice pointer,
but then goes on to require that the same pointer matches
VLANClientState::opaque.
That is no longer the case for virtio-net since qdev and wasn't
previously the case for rtl8139, ne2k_pci or eepro100.
Make the situation a lot more clear by maintaining a VLANClientState
pointer in NICInfo.
