include: never overwrite realInputProc with enqueueInputProc. Bug #13511
    
    In some cases (triggered by a key repeat during a sync grab) XKB unwrapping
    can overwrite the device's realInputProc with the enqueueInputProc. When the
    grab is released and the events are replayed, we end up in an infinite loop.
    Each event is replayed and in replaying pushed to the end of the queue again.
    
    This fix is a hack only. It ensures that the realInputProc is never
    overwritten with the enqueueInputProc.
    
    This fixes Bug #13511 (https://bugs.freedesktop.org/show_bug.cgi?id=13511)
    (cherry picked from commit eace88989c3b65d5c20e9f37ea9b23c7c8e19335)
