[PATCH 5.19 345/717] ASoC: wm5102: Fix PM disable depth imbalance in wm5102_probe

From: Zhang Qilong <zhangqilong3@huawei.com>

[ Upstream commit fcbb60820cd3008bb44334a0395e5e57ccb77329 ]

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 wm5102_probe.

Fixes:93e8791dd34ca ("ASoC: wm5102: Initial driver")
