[PATCH v0 2/3] usb-storage: isd200: fix initFunction error return

[PATCH v0 2/3] usb-storage: isd200: fix initFunction error return

[Lin Ma]

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.
