[RADA2B] No errors reported when the A2B bus is lost and does not recover when reconnected.

[bigcmos]

Test:

1. [t=0m0s] Start recording Audio
2. [t=0m35s] Disconnected the A2B bus cable between a single mic and the RADA2B
3. [t=0m45s] Reconnect the A2B cable
4. [t=1m55s] Disconnect network cable
5. [t=2m08s] Reconnect network cable
6. [t=2m17s] Disconnect network cable
7. [t=2m27s] Reconnect network cable

Expect: While the A2B or network cable is disconnected an error should be reported and no audio data is sent. When the cable is reconnected the error should be cleared and the Audio should resume.

Actual:
[FAIL] After the A2B cable is disconnected no errors are reported. Audio sends the same value continuously for every sample. Audio stream doesn't recover after the A2B cable is reconnected.
[SUCCESS] A disconnect and reconnect error is reported for the network cable.

Code snippet for event filtering that we expect to return errors:

    icsneo::RADA2B *icsneo_pointer;  // Created and initialized elsewhere.
    icsneo::EventCallback callback(
        [this](std::shared_ptr<icsneo::APIEvent> event) { this->event_callback(event); },
        std::make_shared<icsneo::EventFilter>(icsneo_pointer));
    event_callback_id_ = icsneo::EventManager::GetInstance().addEventCallback(callback);

Output of callback messages

Audio Sample during test. Disconnect of A2B bus happens around 35 second mark.
