    nvmm: Fix VMX VMCS remote clear issues
    
    When clearing a VMCS from a remote CPU, must wait for the IPI to
    complete.  Otherwise the VMCS may be wrong when the thread migrates to
    another CPU and thus cause panics when executing VMX instructions.
    
    Credit to Matt Dillon for the debugging and fix.
