sde: KeyLocker insns with ZF output look to only ever set it

It looks as if ZF would only ever get set for insns where this indicates a failure of some sort, but not clear it upon success. I've observed to with at least ENCODEKEY128 and AESENC128KL, and prefixing the insns with "test esp,esp" allows to work around the issue.

Can you confirm this behavior? If so, is it possible to have an indication as to when a fix would be available?

This should be fixed in the new release that we posted.

This looks to be worse upon further extension of the code I'm writing: The other status flags also look to not get cleared.
