ASoC: codecs: hdac_hdmi: Fix incorrect use of list_for_each_entry
[ Upstream commit 326b509238171d37402dbe308e154cc234ed1960 ]
If we don't find any pcm, pcm will point at address at an offset from
the the list head and not a meaningful structure. Fix this by returning
correct pcm if found and NULL if not. Found with coccinelle.
