dmaengine: stm32-dmamux: Fix PM usage counter unbalance in stm32 dmam…
…ux ops [ Upstream commit baa1637 ] pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. We fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced.
