    elf: Fix a DTV setup issue [BZ #27136]

    The max modid is a valid index in the dtv, it should not be skipped.

    The bug is observable if the last module has modid == 64 and its

    generation is same or less than the max generation of the previous

    modules.  Then dtv[0].counter implies dtv[64] is initialized but

    it isn't. Fixes bug 27136.
