usb-storage: alauda: fix initFunction error return

Browse Source 
The initFunction is called when probing a new device, its call relation
is like:

USB core: probe() -> usb_stor_probe2() -> usb_stor_acquire_resources()
-> init_alauda()

That is, the error return of the initFunction should tell USB core what
happened instead of using error code like USB_STOR_TRANSPORT_ERROR.
