ALSA: hda - Fix superfluous HDMI jack repoll
The recent commit [e90247f9fcee: ALSA: hda - Split ELD update code
from hdmi_present_sense()] rewrote the HDMI jack handling code, but a
slight behavior change sneaked in unexpectedly. When the jack isn't
connected, it tries repoll unnecessarily.
This patch addresses the flaw, to the right behavior as before.
Fixes: e90247f9fcee ('ALSA: hda - Split ELD update code from hdmi_present_sense()')
