For instance, during interleaved discovery, when we are about to start inquiry, the state machine forcibly goes to DISCOVERY_STOPPED while it should stay in DISCOVERY_FINDING state. This problem results in unexpected behaviors such as sending two mgmt_discovering events to userspace (when only one event is expected) and Stop Discovery failures.
