dmaengine: ste_dma40: Fix PM disable depth imbalance in d40_probe
[ Upstream commit 0618c077a8c20e8c81e367988f70f7e32bb5a717 ]
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 calling pm_runtime_disable when error returns.
