CONTAP-292560: RFE: Cancel a deferred giveback if autogiveback is disabled
Issue
If giveback is deferred, and autogiveback is disabled, the giveback should be canceled.
The observed behavior:
1. auto-giveback and auto-giveback-after-panic enabled
2. Panic and takeover
3. Giveback is deferred (node is not WFG)
4. auto-giveback and auto-giveback-after-panic disabled
5. Impaired node is booted to WFG
6. Auto-giveback is triggered, despite being disabled
The logic may fit customer expectations better if disabling auto-giveback after takeover (and attempting, but not completed, giveback) also cancels the deferred giveback.
