usb: wusbcore: use USB_CTRL_SET_TIMEOUT and USB_CTRL_GET_TIMEOUT
Use USB_CTRL_SET_TIMEOUT and USB_CTRL_GET_TIMEOUT for USB control messages instead of an arbitrary 1s timeout value. This is particularly useful for WUSB since in the worst case RF scanario, a WUSB device can be unresponsive for up to 4s and still be connected.
