Log:
  virtio_pci(4): Fix typo in read_ivar method
  
  Prior to this revision, vtpci's BUS_READ_IVAR method on VIRTIO_IVAR_SUBVENDOR
  accidentally returned the PCI subdevice.
  
  The typo seems to have been introduced with the original commit adding
  VIRTIO_IVAR_{{SUB,}DEVICE,{SUB,}VENDOR} to virtio_pci.  The commit log and code
  strongly suggest that the ivar was intended to return the subvendor rather than
  the subdevice; it was likely just a copy/paste mistake.
  
  Go ahead and rectify that.
