hwmon: (acpi_power_meter) Don't crash the kernel unnecessarily

Browse Source 
acpi_power_meter crashes the kernel if it detects an unexpected event
or an internal implementation error. While the detected conditions
suggest that there is a bug in the code, the condition is not fatal.
Replace BUG() with WARN().
