When runtime resume is for system suspend, hda_codec_jack_check() schedules jackpoll_work which uses snd_hdac_is_power_on() to check whether codec is suspended.

If we were to use snd_hdac_is_power_on() in system PM path, pm_runtime_status_suspended() should be used instead of pm_runtime_suspended(), otherwise pm_runtime_{enable,disable}() changes the result of snd_hdac_is_power_on().

Because devices suspend in reverse order (i.e. child first), it doesn't make much sense to resume already suspended codec from audio controller.

So instead of using pm_runtime_status_suspended(), the better approach here is to make sure jackpoll isn't used in system PM process.

Fixes: 215a22ed31a1 ("ALSA: hda: Refactor codec PM to use direct-complete optimization") --- v3: Clarify the root cause and why it's needed. v2: No change.
