[PATCH -next 1/4] ASoC: wm8997: Fix PM disable depth imbalance in wm8997_probe

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 wm8997_probe
