nohz: Remove update_ts_time_stat from tick_nohz_start_idle

There is no reason to call update_ts_time_stat from tick_nohz_start_idle
anymore (after 05083290 sched: Eliminate the ts->idle_lastupdate field)
when we updated idle_lastupdate unconditionally.

We haven't set idle_active yet and do not provide last_update_time so
the whole call end up being just 2 wasted branches.
