module_reload: remove snd_hda_intel
The audio driver uses the power well provided by our driver, so on
Haswell we can't "rmmod i915" if we don't "rmmod snd_hda_intel" first.
The problem with removing snd_hda_intel is that we also need to kill
its users. On the specific machine I tested, the only user seem to be
alsactl, but on other machines this may change. IMHO we should leave
the "kill user space" step to whoever is running the script, but
Daniel asked me to put it here so we have a better chance of Just
Working on QA's machines.
