Peter Zijlstra 8edfb0362e hrtimer: Fix hrtimer_is_queued() hole ...

A queued hrtimer that gets restarted (hrtimer_start*() while
hrtimer_is_queued()) will briefly appear as unqueued/inactive, even
though the timer has always been active, we just moved it.

Close this hole by preserving timer->state in
hrtimer_start_range_ns()'s remove_hrtimer() call.
