Alexander Egorenkov 025a2198a4 zdump/dfi_s390: Fix use of uninitialized stack value in mem_chunks_add_ext() ...

If the while loop in mem_chunks_add_ext() is never executed, then
the stack variable containing the dump segment header will never be
initialized.

clang's static code analyzer reports the following problem:

$ make CC="clang --analyze" -C zdump

dfi_s390.c:157:6: warning: Branch condition evaluates to a garbage value [core.uninitialized.Branch]
        if (!dump_segm.stop_marker)
            ^~~~~~~~~~~~~~~~~~~~~~
