Bluetooth: Controller: Rework instant based procedure complete event

Browse source 
Rework instant based procedure complete event generation to be
held until after the on-air instant has elapsed, to have
conditional compilation around the code where the event
generation be held or immediately dispatched so that it
improves readability.
