pm_runtime_get_sync will increment the PM reference count
even failed. Forgetting to putting operation will result
in a reference leak here. 

Replace it with pm_runtime_resume_and_get to keep usage
counter balanced. 

BTW, pm_runtime_resume_and_get is introduced in v5.10-rc5 as
dd8088d5a896 ("PM: runtime: Add  pm_runtime_resume_and_get
to dealwith usage counter")
