Bluetooth: host: Refactor use of #ifdef to IS_ENABLED()

Browse source 
Refactor use of #ifdef to IS_ENABLED() pattern for handling cancellation
of outgoing connection attempt. Reduce the amount of indentation by
combining outer if-statements.
Move handling of canceled create connection into a helper function.
