I wouldn't call it a bug, since the quirk that is "live" during
suspend/resume is not the only quirk needed to make the mic work.
Anyway, more testing shows that one step in my sequence was not needed.

The whole story is:

1/ modprobe snd-hda-intel model=,dell-headset-multi
But **with a headset plugged in in the combo jack**. Else it does not work.
At this point the headset mic works but not the internal one.

2/ rmmod snd-hda-intel. The headset can be removed now, or not.

3/ modprobe snd-hda-intel model=,headset-mic

4/ Now the proper boost and recording levels can be set in alsamixer,
the mic works.

5/suspend-resume. Mic stops working.
