greybus: camera: Fix size of configure_streams(0)

Browse Source 
When APB-A CSI-Tx configuration fails, it is necessary to unconfigure
the camera module issuesing a 0 stream configuration request.
Fix size of request and response to avoid Greybus core complain about
Response size differences.

Testing Done: Triggering the error condition after APB-A CSI-tx
              configuration does not make Greybus core complain anymore
