virtio-serial-bus: Fix bus initialisation and allow for bus identification

This commit enables one to use multiple virtio-serial devices and to
assign ports to arbitrary devices like this:

  -device virtio-serial,id=foo -device virtio-serial,id=bar \
  -device virtserialport,bus=foo.0,name=foo \
  -device virtserialport,bus=bar.0,name=bar
