In DxeCheckBootVariable.c, add check for BootOrder and Variable
that return EFI_NOT_FOUND when they are NULL.
In DxeCheckGcd.c, add check for GcdIoMap to ensure it not NULL
when allocating memory to what it points to.

I think we should continue the loop when BootOrder == NULL, we should not just return.
Suggest to combine the condition check in following line:
If (EFI_ERROR(Status) || (BootOrder == NULL)) {
continue;
}

Same here, I think we should not return directly.
Combine the check in following line:
If (!EFI_ERROR(Status) && (Variable != NULL)) {
DumpKeyOption (...);
else {
