hwmon: (acpi_power_meter) Fix a check for the return value of read_domain_devices().
After commit fabb1f813ec0 ("hwmon: (acpi_power_meter) Fix fail to load
module on platform without _PMD method"),
the acpi_power_meter driver fails to load if the platform has _PMD method.
To address this, add a check for successful read_domain_devices().
Tested on Nvidia Grace machine.
