When unplugging RTL8152 Fast Ethernet Adapter which is plugged
into an USB HUB, the driver would get -EPROTO for bulk transfer.
There is a high probability to get the soft/hard lockup
information if the driver continues to submit Rx before the HUB
completes the detection of all hub ports and issue the
disconnect event.

I don't think it is a good idea.
For the other situations which return the same error code, you would stop the rx, too.
However, the rx may re-work after being resubmitted for the other cases.
