PM: sleep: Adjust check before setting power.must_resume
[ Upstream commit eeb87d17aceab7803a5a5bcb6cf2817b745157cf ]
The check before setting power.must_resume in device_suspend_noirq()
does not take power.child_count into account, but it should do that, so
use pm_runtime_need_not_resume() in it for this purpose and adjust the
comment next to it accordingly.
