      block: Introduce bs->zero_beyond_eof · 0d51b4de

      In 4146b46c42e0989cb5842e04d88ab6ccb1713a48 (block: Produce zeros when
      protocols reading beyond end of file), we break qemu-iotests ./check
      -qcow2 022. This happens because qcow2 temporarily sets ->growable = 1
      for vmstate accesses (which are stored beyond the end of regular image
      data).
      
      We introduce the bs->zero_beyond_eof to allow qcow2_load_vmstate() to
      disable ->zero_beyond_eof temporarily in addition to enable ->growable.
      
      [Since the broken patch "block: Produce zeros when protocols reading
      beyond end of file" has not been merged yet, I have applied this fix
      *first* and will then apply the next patch to keep the tree bisectable.
