platform/x86: fujitsu-laptop: simplify set_lcd_level()
acpi_execute_simple_method() takes a method parameter which tells it to
look for the given method underneath the given handle, so calling
acpi_get_handle() beforehand is redundant. Replace the call to
acpi_get_handle() with a call to acpi_execute_simple_method(), thus
eliminating the need for a local variable storing the handle. Update
debug message to reflect this change. Also do not assign a default
value to status as it has no influence on execution flow.
