[PATCH -next] media: sun8i: Fix PM reference leak in deinterlace_start_streaming()

[Lu Jialin]

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.
