acpi_fujitsu_hotkey_notify() is pretty deeply nested, which hurts readability. Move the keycode processing part to two separate functions to make the code easier to understand and save a few line breaks. Rename variable keycode_r to keycode as there is no longer any need to differentiate between the two. Tweak indentations to make checkpatch happy.
