usb-storage: isd200: fix initFunction error return
The initFunction is called when probing a new device, its call relation is like: USB core: probe() -> usb_stor_probe2() -> usb_stor_acquire_resources() -> isd200_init_info() That is, the error return of the initFunction should tell USB core what happened instead of using custom error code like ISD200_ERROR.
