usb-core: Set intfdata to NULL if a driver's probe method failed
Ensure that intfdata always is NULL if no driver is bound: 1) drvdata is for a driver to store a pointer to driver specific data 2) If no driver is bound, there is no driver specific data associated with the device 3) Thus logically drvdata should be NULL if no driver is bound. We already set intfdata to NULL when a driver is unbound, to ensure that intfdata will be NULL even if the drivers disconnect method does not properly clear it. This ensures that intfdata will also be NULL after a failed probe, even if the driver's probe method left a (likely dangling) pointer in there.
