mmc: block: Do not lose cache flush during CQE error recovery
stable inclusion from stable-v6.6.5 commit c77590974d9633d612252ac7be7d514d80f83a21 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8N21P Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=c77590974d9633d612252ac7be7d514d80f83a21 -------------------------------- commit 174925d340aac55296318e43fd96c0e1d196e105 upstream. 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.
