ANDROID: cpu: correct dl_cpu_busy() calls

Browse Source 
The patch 0039189a3b ("sched/deadline: Merge
dl_task_can_attach() and dl_cpu_busy()") which is picked from
upstream modifies declaration of function dl_cpu_busy().
But it won't update function usage from android specific code
that introduced with patch 683010f555 ("ANDROID: cpu/hotplug:
add pause/resume_cpus interface").

Bug: 266874695
Fixes: 0039189a3b ("sched/deadline: Merge dl_task_can_attach() and dl_cpu_busy()"
