hwmon: (acpi_power_meter) Fix compiler warning seen in some configurations
In some configurations, BUG() does not result in an endless loop but returns to the caller. This results in the following compiler warning: drivers/hwmon/acpi_power_meter.c: In function 'show_str': drivers/hwmon/acpi_power_meter.c:380: warning: 'val' may be used uninitialized in this function Fix the warning by setting val to an empty string after BUG().
