Remove use of the enable_queuing_profile_connection_change flag in Scan Manager.

This change flags a bug fix required for 24Q1 Release. Since the flags havent been through trunkfood we don't have enough time to soak it behind a flag.
This fix has already been tested and soaked in ATK so is expected to work fine without flagging.
