ALSA: hda - Fix static checker warning in patch_hdmi.c

Browse source

commit 360a824568 upstream.

The static checker warning is:

	sound/pci/hda/patch_hdmi.c:460 hdmi_eld_ctl_get()
	error: __memcpy() 'eld->eld_buffer' too small (256 vs 512)

I have a hard time figuring out if this can ever cause an information leak
(I don't think so), but nonetheless it does not hurt to increase the
robustness of the code.

Fixes: 68e03de985 ('ALSA: hda - hdmi: Do not expose eld data when eld is invalid')
