mmc: block: Do not lose cache flush during CQE error recovery
During CQE error recovery, error-free data commands get requeued if there
is any data left to transfer, but non-data commands are completed even
though they have not been processed. Requeue them instead.
Note the only non-data command is cache flush, which would have resulted in
a cache flush being lost if it was queued at the time of CQE recovery.
Fixes: 1e8e55b67030 ("mmc: block: Add CQE support")
