[PATCH 1/2] platform/x86: fujitsu-laptop: decrease indentation in acpi_fujitsu_notify()

[MichaÅ KÄpieÅ]

acpi_fujitsu_notify() is pretty deeply nested, which hurts readability.
Strip off one level of indentation by returning early when the event
code supplied as argument is not ACPI_FUJITSU_NOTIFY_CODE1.
