Miaoqian Lin 2c35c95d36 dmaengine: stm32-dmamux: Fix PM disable depth imbalance in stm32_dmamux_probe ...

commit e831c7aba950f3ae94002b10321279654525e5ec upstream.

The pm_runtime_enable will increase power disable depth.
If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable().
