[ Upstream commit 650e723cecf2738dee828564396f3239829aba83 ]

[Why]
For MST case: when update_config is called to disable a stream,
this clears the settings for all the streams on that link.
We should only clear the settings for the stream that was disabled.

[How]
Clear the settings after the call to remove display is called.
