ASoC: wm5102: Fix PM disable depth imbalance in wm5102_probe
[ 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.
