ACPI / battery: Fix warning message in acpi_battery_get_state()

capacity_now should be assigned after comparing it to design_capacity.

Otherwise warning is printed even when capacity_now before assignment is
equal to design_capacity, making the check useless and "current charge level"
wrong (it should be higher than, not equal to, "maximum charge level", which
is full_charge_capacity):

"battery: reported current charge level (56410) is higher than reported
maximum charge level (56410)."
