ACPI: battery: Use kstrtoul() over sscanf("%lu\n")

Browse source

It is more preferred to use kstrto*() to parse a single number. The
function family properly returns an errno on error and is the correct
mechanism to parse data from sysfs.

The number base is set to 10 in order not to break the ABI.
