Benjamin Berg 8552290bec goodix: Reset device if storage listing fails
When opening the device, query the stored prints. This should usually
always succeed (and it should be fast). If it fails, then we are very
likely dealing with a corrupted template storage on the device. In that
case, emit the command to clear the storage in order to reset the device
and get it back into a usable state.
