Bluetooth: Controller: Fix missing supervision/sync lost

Browse source 
When radio event prepare is cancelled due to preemption by
overlapping radio events, the extra done event processing
was missing and hence the use of accumulated prepares'
skip/latency count.
This caused the check for supervision timeout and sync
lost not be aware of the elapsed events.
