[PATCH 5.19 344/717] ASoC: wm5110: Fix PM disable depth imbalance in wm5110_probe

From: Zhang Qilong <zhangqilong3@huawei.com>

[ Upstream commit 86b46bf1feb83898d89a2b4a8d08d21e9ea277a7 ]

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 wm5110_probe.

Fixes:5c6af635fd772 ("ASoC: wm5110: Add audio CODEC driver")
