[mutter/wip/carlosg/coverity-fixes: 4/12] clutter: Turn warning into assert

[Carlos Garnacho <carlosg src gnome org>]

commit a90746515ecc680a735cab950a7ed1748ad6db90

    clutter: Turn warning into assert
    
    This warning is actually dead code, since should_be_mapped and
    must_be_realized are always set to the same value, so it does not
    make sense to check for "a && !b".
    
    Turn this into an assert so we avoid the dead branch, but do not
    remove the variable duplication so the more aptly named variable
    is used where it belongs, for clarity.
    
    CID: #1506254
