Log:
  virtio: Pass the interrupt type in mmio mode
  
  When we register an interrupt handler we need to pass the intr_type along in
  bus_setup_intr().
  
  The interrupt type matters because it is used to decide if we need to enter
  NET_EPOCH. That meant that vtmmio-based if_vtnet did not, which led to panics
  with INVARIANTS set.
