virtio: add PCI device release() function

Add a release() function for virtio_pci devices so as to avoid:

  Device 'virtio0' does not have a release() function, it is broken and must be fixed

Move the code to free the resources associated with the device
from virtio_pci_remove() into this new function. virtio_pci_remove()
now merely unregisters the device which should cause the final
ref to be dropped and virtio_pci_release_dev() to be called.
