[PATCH -next] platform/surface: remove status assignment without reading

[Zou Wei]

The status local variable is assigned but never read:

drivers/platform/surface/surface3-wmi.c:60:14: warning:
variable ‘status’ set but not used [-Wunused-but-set-variable]
  acpi_status status;
              ^~~~~~
