Style incorrectly reports error Code inside a namespace should not be indented

[Jean-Yves Avenard [:jya]]

In a constructor, if we use a method in a namespace like:

```
AudioSampleBufferCompressor::AudioSampleBufferCompressor()
    : m_serialDispatchQueue { WorkQueue::create("com.apple.AudioSampleBufferCompressor") }
    , m_lowWaterTime { PAL::CMTimeMakeWithSeconds(LOW_WATER_TIME_IN_SECONDS, 1000) }
{
}
```

Style EWS complains that:
Code inside a namespace should not be indented.  [whitespace/indent] [4] due to the PAL::CMTimeMakeWithSeconds 

The code above is perfectly valid.
