    platform/x86: wmi: remove unnecessary argument
    
    [ Upstream commit 84eacf7e6413d5e2d2f4f9dddf9216c18a3631cf ]
    
    The GUID block is available for `wmi_create_device()`
    through `wblock->gblock`. Use that consistently in
    the function instead of using a mix of `gblock` and
    `wblock->gblock`.
