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.

I think we don't need that label change, fh still needs to be released
in case of an error.
ret = sensor_set_power(camif, 1);
