ACPI: Don't report current_now if battery reports in mWh

ACPI batteries can report in units of either current or energy. Right
now we expose the current_now file even if the battery is reporting
energy units, resulting in a file that should contain mA instead
containing mW. Don't expose this value unless the battery is reporting
current.
