[media] gspca - main: Handle the xHCI error on usb_set_interface()



This patch is adapted from a patch from Sarah Sharp (2010/05/03).
The xHCD handler checks the USB bandwidth on usb_set_interface()
instead of on usb_submit_urb().
Now, the same treatment is applied in case of error of both functions.
