"FileBuffer" is a non-optional input (pointer) parameter to
DxeImageVerificationHandler(). Normally, when an edk2 function receives a
NULL argument for such a parameter, we return EFI_INVALID_PARAMETER or
RETURN_INVALID_PARAMETER. However, those don't conform to the
SECURITY2_FILE_AUTHENTICATION_HANDLER prototype.
Return EFI_ACCESS_DENIED when "FileBuffer" is NULL; it means that no image
has been loaded.
This patch does not change the control flow in the function, it only
changes the "Status" outcome from API-incompatible error codes to
EFI_ACCESS_DENIED, under some circumstances.
