The doorbell (DB) recovery entries gets deleted by the QED driver when QEDR device transition to non-active or dead state (e.g., during the AER recovery phase). The patch adds driver changes to skip deleting DB recovery entries from QEDR when the device is in non-active state. Fixes: 731815e720ae ("qede: Add support for handling the pcie errors.")
