[ Upstream commit 545b2baac89b859180e51215468c05d85ea8465a ]
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:
1) Replacing it with pm_runtime_resume_and_get to keep usage counter
balanced.
2) Add putting operation before returning error.
