sched/hmp: Disable interrupts when resetting all task stats
Taking the pi_lock without disabling interrupts in reset_all_task_stats()
is problematic. In that an interrupt can end up waking a task which in
turn needs the pi_lock again causing a deadlock. Disable interrupts along
with taking the lock to avoid this problem.
