[mutter/wip/carlosg/coverity-fixes: 5/13] clutter: Turn warning into assert

[Carlos Garnacho <carlosg src gnome org>]

commit 50c074c9016be9cf6ac290aa6dd5362050ad924c

    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
