Log Message:
usb(4): Bus exploration is single-threaded -- assert it so.

New usb_in_event_thread(dev) returns true if dev is a USB device --
that is, a device with a usbN ancestor -- and the current thread is
the USB event thread.

(Kinda kludgey to pass around the device_t instead of, say, struct
usbd_bus, but I don't see a good way to get to the usbN device_t or
struct usb_softc from there.)
