platform/x86: fujitsu-laptop: do not log LED registration failures
If acpi_fujitsu_laptop_leds_register() returns an error, the latter will
become the return value of acpi_fujitsu_laptop_add(), which in turn will
be reported by driver core. Simplify code by replacing pr_err() calls
with return statements. Return 0 instead of result when no errors occur
in order to make the code easier to read.
