The ACPI_HANDLE() macro is a wrapper arond the ACPI_COMPANION()
macro and the ACPI handle produced by the former comes from the
ACPI device object produced by the latter, so it is way more
straightforward to evaluate the latter directly instead of passing
the handle produced by the former to acpi_bus_get_device().
Modify s3_wmi_check_platform_device() accordingly (no intentional
functional impact).

compiler warning
Explicitly check the status rather then relying on output.pointer staying
NULL on an error. This silences the following compiler warning:
drivers/platform/surface/surface3-wmi.c:60:14: warning: variable 'status' set but not used [-Wunused-but-set-variable]
