USB: rename USB_SPEED_VARIABLE to USB_SPEED_WIRELESS

It's really the wireless speed, so rename the thing to make
more sense. Based on a recommendation from David Vrabel

  * reference that we'll drop.

  * First we need to determine if the device is a WUSB device (else we
- * ignore it). For that we use the speed setting (USB_SPEED_VARIABLE)
+ * ignore it). For that we use the speed setting (USB_SPEED_WIRELESS)
  * [FIXME: maybe we'd need something more definitive]. If so, we track
