Subject: ALSA: hda - Fix missing ELD update at unplugging

From: Takashi Iwai <[email protected]>

commit c64c1437afb14ebc900e40910f31ffb20bf652ad upstream.

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.
