[PATCH v3 -next] ASoC: stm: Fix PM disable depth imbalance in stm32_i2s_probe

[Zhang Qilong]

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 moving
pm_runtime_enable to the endding of stm32_i2s_probe.
