[PATCH] dmaengine: tegra-apb: fix reference leak in tegra_dma_issue_pending and tegra_dma_synchronize

pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in a reference leak here. A new function pm_runtime_resume_and_get is introduced in [0] to keep usage counter balanced. So We fix the reference leak by replacing it with new funtion.
