Each condition binding to the same wait should be unique. AOAC code misused
the wait of FW offload series and broke the above rule. It added another
macro to generate wait condition of WoWLAN/AOAC, but the results conflict
to the ones of FW offload series. It means that we might be completed
wrongly in logic. We don't want things work/read like this and should
have avoided this.

Fix this by adding another wait which aims for WoWLAN functions.
