System takes a very long time to suspend after commit 215a22ed31a1
("ALSA: hda: Refactor codec PM to use direct-complete optimization"):

That commit keeps codec suspended during the system suspend. However,
SOF driver's runtime resume, which is for system suspend, calls
hda_codec_jack_check() and schedules jackpoll_work. The jackpoll
work uses snd_hda_power_up_pm() which tries to resume the codec in
system suspend path, hence blocking the suspend process.
So only check jack status if it's not in system PM process.
