USB: janitor storage initializers
We all know that pointless janitoring is bad, but this code is just
offensive. So:
- The error code goes directly to probe return, so don't return -1.
- Don't return return internal usb-storage codes either.
- usb_stor_control_msg takes timeout in milliseconds.
- Sanitize messages.
