ACPI / Battery: remove battery refresh on resume
This partially reverts commit da8aeb92 ("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).
