Attr are EFI_VARIABLE_NON_VOLATILE|VARIABLE_AUTHENTICATED_WRITE_ACCESS, will return EFI_INVALID_PARAMETER. Added one case, only when one attribute is EFI_VARIABLE_NON_VOLATILE will EFI_INVALID_PARAMETER be returned. If attr are EFI_VARIABLE_NON_VOLATILE|VARIABLE_AUTHENTICATED_WRITE_ACCESS will return EFI_UNSUPPORTED. In the UEFI2.7 spec, there is a description as below: EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS is deprecated and should not be used. Platforms should return EFI_UNSUPPORTED if a caller to SetVariable() specifies this attribute.
