When running on the sandbox the stack is not necessarily at a higher memory address than the highest free memory.There is no reason why the checking of the highest memory address should be more restrictive for EFI_ALLOCATE_ANY_PAGES than for EFI_ALLOCATE_MAX_ADDRESS.

This will break on systems that do not map high address space into the linear map (IIRC nvidia systems had that issue).
