media: venus: vdec: use pm_runtime_resume_and_get() 

Commit dd8088d5a8 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
added pm_runtime_resume_and_get() in order to automatically handle
dev->power.usage_count decrement on errors.

Use the new API, in order to cleanup the error check logic.

As a bonus, there's no need to check if ret == 1, as
pm_runtime_resume_and_get() always return 0 on success.
