    util/cbfstool: Initialize elf_writer pointer to avoid crash
    
    If some error happens in cbfs_payload_make_elf, the code jumps to "out",
    and elf_writer_destroy(ew) is called. This may happen before an elf
    writer is allocated.
    To avoid accessing an uninitialized pointer, initialize ew to NULL;
    elf_writer_destroy will perform no action in this case.
