ASoC: hdac_hdmi: don't update the iterator in pcm list remove
Fix not to update the iterator element, instead use list_del to remove
entry from the list.
This fixes the following coccinelle and static checker warning:
sound/soc/codecs/hdac_hdmi.c:1884:2-21:iterator with update on line
1885
sound/soc/codecs/hdac_hdmi.c:2011 hdac_hdmi_dev_remove()
error: potential NULL dereference 'port'.
Fixes: e0e5d3e5a53b('ASoC: hdac_hdmi: Add support for multiple ports to a PCM')
