ASoC: topology: Correct error handling in soc_tplg_dapm_widget_create()

[ Upstream commit 9c363532413cda3e2c6dfa10e5cca7cd221877a0 ]

Academic correction of error handling:
In case the allocation of kc or kcontrol_type fails the correct label to
jump is hdr_err since the template.sname has been also allocated at this
point.
