scsi: return ENODEV in scsi_get_blk_by_uuid()

Change scsi_get_blk_by_uuid() to return -ENODEV instead of -1 on error.
Other scsi_* functions return an error code rather than -1.

1 is EPERM, which doesn't make sense here. So we use ENODEV instead. The
only caller only checks for !success, so changing the value has no
effect on the caller.
