REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4341
Commit 21320ef66989 broke some tests in the AuthVar_Conf test
in edk2-test. There are 2 testcases that invoke SetVariable
with the following attribute value:
(EFI_VARIABLE_NON_VOLATILE | EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS)
EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS is deprecated and the UEFI spec
says this should return EFI_UNSUPPORTED.
