ACPI: battery: Sanitise model_number by dropping unprintable characters
The battery Embedded Controller (EC) may return the model name with
trailing unprintable or non-ASCII characters. For example, on some
systems:
$ cat /sys/class/power_supply/BAT0/model_name
LNV-5B10W51864��
If a non-ASCII or an unprintable character is found, it will be
replaced with '\0' to ensure the model_number is a valid string.
If left intact, the malformed string prevents udev rules and hwdb
working correctly.
