Commit f6b139b added return status handling to PciIo->Mem.Write.
However, the second status handling will override EFI_DEVICE_ERROR
returned in this branch:
//
// Check the NVMe cmd execution result
//
if (Status != EFI_TIMEOUT) {
if ((Cq->Sct == 0) && (Cq->Sc == 0)) {
Status = EFI_SUCCESS;
} else {
Status = EFI_DEVICE_ERROR;
^^^^^^^^^^^^^^^^
Since PciIo->Mem.Write will probably return SUCCESS, it causes
NvmExpressPassThru to return SUCCESS even when DEVICE_ERROR occurs.
Callers of NvmExpressPassThru will then continue executing which may
cause further unexpected results, e.g. DiscoverAllNamespaces couldn't
break out the loop.
So we save previous status before calling PciIo->Mem.Write and restore
the previous one if it already contains error.
