tick: Mark sched_timer to expire in hard interrupt context 

sched_timer must be initialized with the _HARD mode suffix to ensure expiry
in hard interrupt context on RT.

The previous conversion to HARD expiry mode missed on one instance in
tick_nohz_switch_to_nohz(). Fix it up.

Fixes: 902a9f9c50 ("tick: Mark tick related hrtimers to expiry in hard interrupt context")
