Remove the limit of state machines in Bluetooth BLE profiles

The limit of state machines was added to avoid DoS attack. However, it is not necessary because the state machines are created only when a device is connected. The number of connected BLE devices is limited by the Bluetooth controller and system property. Therefore, the limit of state machines is not necessary.
This CL removes the limit of state machines in Bluetooth BLE profiles.
