usb-storage: apply IGNORE_UAS only for HIKSEMI MD202 on RTL9210

commit dbd24ec17b upstream.

The commit e00b488e81 ("usb-storage: Add Hiksemi USB3-FW to IGNORE_UAS")
blacklists UAS for all of RTL9210 enclosures.

The RTL9210 controller was advertised with UAS since its release back in
2019 and was shipped with a lot of enclosure products with different
firmware combinations.

Blacklist UAS only for HIKSEMI MD202.

This should hopefully be replaced with more robust method than just
comparing strings.  But with limited information [1] provided thus far
(dmesg when the device is plugged in, which includes manufacturer and
product, but no lsusb -v to compare against), this is the best we can do
for now.
