[PATCH] sched/core: Remove useless hrtimer_active check

[Daniel Lezcano]

The function tick_clear() checks if the timer is active and in this case
cancels the timer. However, hrtimer_cancel does the same check.

Perhaps, this test is made on purpose to skip some function calls for
efficiency reasons but if it is not the case we can safely remove it.
