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.

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.
