ACPI: battery: Don't return -EFAIL on broken packages.
Acer BIOS has a bug which is exposed when a dead battery is present.
The package template that is used to describe battery status is
over-written with sane values when the battery is live.
But when the batter is dead, a bogus reference in the template
is used. In this case, Linux returns a fault, when instead
it should simply return that it doesn't know the missing value.
