Yu Kuai 83eb4868d3 dmaengine: stm32-mdma: fix PM reference leak in stm32_mdma_alloc_chan_resourc() ...

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage
counter balanced.
