    platform/x86: wmi: remove unnecessary initializations
    
    [ Upstream commit 43aacf838ef7384d985ef5385ecb0124f8c70007 ]
    
    Some pointers are initialized when they are defined,
    but they are almost immediately reassigned in the
    following lines. Remove these superfluous assignments.
