[mamueluth]

The logic in informing user about rt capabilities had logic error. User was informed that rt scheduling is set up when in fact is not setup.

@mamueluth, all pull requests must be targeted towards the master development branch.
Once merged into master, it is possible to backport to humble, but it must be in master
to have these changes reflected into new distributions.
