[PATCH v2 2/3] sched/deadline: Use __sub_running_bw() throughout dl_change_utilization()

[Dietmar Eggemann]

dl_change_utilization() has a BUG_ON() to check that no schedutil
kthread (sugov) is entering this function. So instead of calling
sub_running_bw() which checks for the special entity related to a
sugov thread, call the underlying function __sub_running_bw().
