platform/x86: acer-wmi: reject missing gaming WMI results
WMI_gaming_execute_u32_u64() returns success when firmware supplies
no output object, leaving the caller output untouched. Gaming getters
then inspect an uninitialized result value.
When the caller requests an output value, return -ENOMSG if firmware
supplies no object. Preserve a NULL output pointer as the supported way
for callers to ignore the result.
