usb: storage: ignore bogus device raised by JieLi BR21 USB sound chip



commit a6555cb1cb69db479d0760e392c175ba32426842 upstream.

JieLi tends to use SCSI via USB Mass Storage to implement their own
proprietary commands instead of implementing another USB interface.
Enumerating it as a generic mass storage device will lead to a Hardware
Error sense key get reported.

Ignore this bogus device to prevent appearing a unusable sdX device
file.
