Public bug reported:
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.
