virtio: pci: Tear down VQs in virtio_pci_reset()

The pages backing the virtqueues for virtio PCI devices are not freed
on reset, despite the virtqueue structure being freed as part of the
driver '->priv_auto' destruction at ->remove() time.

Call virtio_pci_del_vqs() from virtio_pci_reset() to free the virtqueue
pages before freeing the virtqueue structure itself.
