Fix PM disable depth imbalance in stm32 probe
Merge series from Zhang Qilong <zhangqilong3@huawei.com>: The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced. We fix it by moving pm_runtime_enable to the endding of probe.
