ASoC: pcm512x: Fix PM disable depth imbalance in pcm512x_probe

[ Upstream commit 97b801be6f8e53676b9f2b105f54e35c745c1b22 ]

The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context. We fix it by going to
err_pm instead of err_clk.
