[PATCH] ASoC: fsl: Fix PM disable depth imbalance in fsl_easrc_probe

[Zhang Shurong]

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 calling
pm_runtime_disable when error returns.
