media: i2c: ov5647: use pm_runtime_resume_and_get()
Commit dd8088d5a896 ("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.
