    Fill in mods/group->effective in XIQueryPointer()
    
    the other XIModifierState/XIGroupState fields are being set correctly,
    but the "effective" field was being left as undefined memory.

    Fix passive grabs.
    
    _XIPassiveGrabDevice, which is called by alle the passive grab functions,
    wrongly returns an error when it shouldn't.
    The attached patch adds the missing "not" to properly test the error
    condition of _XReply.
