[PATCH 2/2] USB: core: rename usb_driver_claim_interface() data parameter

It's been almost twenty years since the interface "private data" pointer
was removed in favour of using the driver-data pointer of struct device.

Let's rename the driver-data parameter of usb_driver_claim_interface()
so that it better reflects how it's used.
