Bluetooth: btusb: fix bInterval for high/super speed isochronous endpoints
For high-speed/super-speed isochronous endpoints, the bInterval
value is used as exponent, 2^(bInterval-1). Luckily we have
usb_fill_int_urb() function that handles it correctly. So we just
call this function to fill in the RX URB.
