hwmon: (hp-wmi-sensors) Fix failure to load on EliteDesk 800 G6
The EliteDesk 800 G6 stores a raw WMI string within the ACPI object in its
BIOS corresponding to one instance of HPBIOS_PlatformEvents.Name. This is
evidently a valid way of representing a WMI data item as far as the
Microsoft ACPI-WMI mapper is concerned, but is preventing the driver from
loading.
This seems quite rare, but add support for such strings. Treating this as a
quirk pretty much means adding that support anyway.
Also clean up an oversight in update_numeric_sensor_from_wobj() in which
the result of hp_wmi_strdup() was being used without error checking.
