platform/x86: mxm-wmi: fix memleak in mxm_wmi_call_mx[ds|mx]()

In the Linux kernel, the following vulnerability has been resolved:

platform/x86: mxm-wmi: fix memleak in mxm_wmi_call_mx[ds|mx]()

The ACPI buffer memory (out.pointer) returned by wmi_evaluate_method()
is not freed after the call, so it leads to memory leak.

The method results in ACPI buffer is not used, so just pass NULL to
wmi_evaluate_method() which fixes the memory leak.
