Bug description:
  Description:  qdio: don't retry EQBS after CCQ 96

  Symptom:      Queue stalls, over-/underreporting of buffer errors.

  Problem:      Immediate retry of EQBS after CCQ 96 means that we
                potentially misreport the state of buffers inspected
                during the first EQBS call.

  Solution:     On CCQ 96, first process the discovered state.
                Afterwards, higher-level code will eventually trigger an
                EQBS/inspection of the remaining buffers. Their state is
                now processed independently from the state that was
                discovered during the first EQBS.
