    uvideo(4): Fix USB interface numbering.

    Don't try to be clever and count -- just use bInterfaceNumber.

    The previous logic to count interface descriptors failed to consider
    interfaces with alternate settings, which led it to pass an invalid
    interface number to usbd_device2interface_handle.

    It is simpler to just use the recorded bInterfaceNumber, which is
    guaranteed by the USB spec to be zero-indexed and below
    bNumInterfaces as we need.
