[ 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.

Fixes: d29d41e28eea6 ("ASoC: topology: Add support for multiple kcontrol types to a widget")
