    rootless: Fix bogus handling of broken root clip · fa0bb018
    Adam Jackson authored
    gcc quite correctly complains about this:
    
        In file included from ../../include/scrnintstr.h:51:0,
                         from rootlessValTree.c:98:
        In function 'RegionUninit.isra.1',
            inlined from 'RegionEmpty' at ../../include/regionstr.h:194:5,
            inlined from 'RootlessMiValidateTree' at rootlessValTree.c:490:9:
        ../../include/regionstr.h:166:9: warning: attempt to free a non-heap object 'RegionBrokenData' [-Wfree-nonheap-object]
                 free((_pReg)->data);
    
    So that'd crash if you ever got there.  RegionNull will do almost the
    same thing only without the free(), so let's do that instead; it might
    still not be an entirely sane way to recover, but it at least won't
    crash.
