    USB: fix usb_reset_device and usb_reset_composite_device(take 3) · 742120c6

    This patch renames the existing usb_reset_device in hub.c to
    usb_reset_and_verify_device and renames the existing
    usb_reset_composite_device to usb_reset_device. Also the new
    usb_reset_and_verify_device does't need to be EXPORTED .
    
    The idea of the patch is that external interface driver
    should warn the other interfaces' driver of the same
    device before and after reseting the usb device. One interface
    driver shoud call _old_ usb_reset_composite_device instead of
    _old_ usb_reset_device since it can't assume the device contains
    only one interface. The _old_ usb_reset_composite_device
    is safe for single interface device also. we rename the two
    functions to make the change easily.
    
    This patch is under guideline from Alan Stern.
