ACPI / PM: Fix error code path for power resources initialization Commit 781d737 (ACPI: Drop power resources driver) introduced a bug in the power resources initialization error code path causing a NULL pointer to be referenced in acpi_release_power_resource() if there's an error triggering a jump to the 'err' label in acpi_add_power_resource(). This happens because the list_node field of struct acpi_power_resource has not been initialized yet at this point and doing a list_del() on it is a bad idea. To prevent this problem from occuring, initialize the list_node field of struct acpi_power_resource upfront.
