What do we do about the cpuidle stats in that case?
I'm thinking primiarly about last_residency_ns and rejected here.

As the idle entry will not happen (call_cpuidle() is not invoked)
the stats would also not required to be updated.

I agree, with the IPI pending it is like the idle task should have not be scheduled, so the idle call is aborted.
