ACPI / Battery: remove battery refresh on resume
This partially reverts commit da8aeb92d4
("ACPI / Battery: Update information on info notification and resume"),
which causes a hang on resume on at least some machines.
This bug was bisected on an ASUS EeePC 901, which hangs at resume time
if we do that "acpi_battery_refresh(battery)" in the battery resume
function.
Rafael suspects we'll still need to refresh the sysfs files upon resume,
but that that can be done from a PM notifier (that will run after
thawing user space).
