If active_bases already has entry for a particular clock type, then we don't need to rewrite it while queuing a hrtimer.
Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> --- Initially I thought of doing this but then thought better remove active_bases completely and so didn't sent this one. Now it might find some place for itself :).
