platform/x86: asus-wmi: Simplify the keyboard brightness updating process
The original asus-wmi queues a work which calls the ACPI/WMI methods to update the keyboard LED brightness. Similar drivers - acer-wmi, dell-wmi-led just call the ACPI/WMI methods directly without workqueues. This patch simplifies the keyboard brightness updating process which calls the kbd_led_update function directly without workqueue in asus-wmi.
