Bluetooth: controller: store STO value instead of pre-calculated reload

Browse source 
Instead of storing the calculated reload value (in conn intervals) in
the conn object, now store the timeout value, and perform calculation
when used. This allows using the timeout value across all CIS's without
having to re-calc and store on change of TO
