ALSA: hda: Keep PM disablement for deny-listed instance

Browse source

We have a runtime PM deny-list for the devices that show the problems
(typically click noises) at runtime suspend/resume, and when it
matches, the driver disables the default runtime PM.  However, we
still allow the runtime PM changed via power_save module option
dynamically, and the desktop system often tweaks it.  This ended up
with a re-enablement of the runtime PM that surprises users, suddenly
suffering from the noises.

This patch changes the driver behavior slightly: when the device is
listed in the deny-list, ignore the power_save option change and keep
the original (that is, off) runtime PM state.
