tick-sched: Check tick_nohz_enabled in tick_nohz_switch_to_nohz()
commit27630532ef
upstream. Since commitd689fe222
(NOHZ: Check for nohz active instead of nohz enabled) the tick_nohz_switch_to_nohz() function returns because it checks for the tick_nohz_active flag. This can't be set, because the function itself sets it. Undo the change in tick_nohz_switch_to_nohz().
