[PATCH 2/3] ASoC: wm8997: Fix PM disable depth imbalance on error

[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.

Fixes: 31833ead95c2c ("ASoC: arizona: Move request of speaker IRQs into bus probe")
