ALSA: hda - Downgrade error message for single-cmd fallback
[ Upstream commit 475feec0c41ad71cb7d02f0310e56256606b57c5 ]
We made the error message for the CORB/RIRB communication clearer by
upgrading to dev_WARN() so that user can notice better. But this
struck us like a boomerang: now it caught syzbot and reported back as
a fatal issue although it's not really any too serious bug that worth
for stopping the whole system.
OK, OK, let's be softy, downgrade it to the standard dev_err() again.
