hal-api-power: Add an error handler to check return value

Add an error handler to check return value of hal_common_put_backend_v2().
Previously, hal_power_put_backend() always return 0 regardless of error.
It adds an error handler and returns negative value
when hal_power_put_backend() fails to put backend.
