Won't there be a similar problem now with the watchdog starting too early?

We need to be better at making sure we don't have a link check watchdog go off while we're shutting things down, so let's stop the timer as soon as we start the remove. Meanwhile, since that was the only thing in ionic_dev_teardown(), simplify and remove that function.
