Subject[ 133/149] Bluetooth: btusb: fix bInterval for high/super speed isochronous endpoints
3.2-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Bing Zhao <bzhao@marvell.com>

commit fa0fb93f2ac308a76fa64eb57c18511dadf97089 upstream.

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.
