ASoC: pcm512x: Fix unbalanced regulator enable call in probe error path
commit ac0a68997935c4acb92eaae5ad8982e0bb432d56 upstream.
When we get a clock error during probe we have to call
regulator_bulk_disable before bailing out, otherwise we trigger
a warning in regulator_put.
Fix this by using "goto err" like in the error cases above.
