Ah.. good catch. I was not aware that EFI_VARIABLE_ATTRIBUTES_MASK doesn't include EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS bit. Thanks for fixing the issue, JunX1 Li and xueshengfeng. Moreover, I assumed that you haven't got Edhaya's and Samer's review, right? If so, you should use "Cc:" instead of "Reviewed-by:" in your commit message.
The code change looks good to me.

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.
