Camera: Use default value in case new value is not supported

- Instead of throwing exception in case of new value is not supported,
just use the default one
- The scenario for fixed issue is:
1. Start back camera
2. Select some scene mode that doesn't overwrite focus mode
3. Go to video mode
4. Switch to front camera (focus mode is change to continuous video
    automatically, based on supported values)
5. Switch to back camera (focus mode is still video)
6. Switch to image mode (focus mode continuous is still selected,
    but not supported for image)
