[ Upstream commit b9a0da5b2edcae2a901b85c8cc42efc5bec4bd7b ]
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_adfsdm_probe.
Fixes:98e500a12f934 ("ASoC: stm32: dfsdm: add pm_runtime support for audio")
