<pre>Looks like a different issue. I believe the problem here is due to a known
issue in the unload path where we call uc_sanitize before we call
intel_uc_fini_hw and therefore we hit the !intel_guc_is_loaded(guc) check in
the latter, thus skipping the guc_disable_communication(). We saw this issue
with guc submission enabled (because we skip the intel_guc_submission_disable
call) and Fernando was looking at fixing it, we just didn't realize there was
an implication on the non-submission path as well.</pre>
