ALSA: hda - Fix missing ELD update at unplugging
i915 get_eld ops may return an error when no encoder is connected, and currently we regard the error as fatal and skip the whole ELD handling. This ended up with the missing ELD update at unplugging. This patch fixes the issue by treating the error as the unplugged state, instead of skipping the rest.
