[PATCH 2/2] hw/net/opencores_eth: Remove unnecessary address masking

[Philippe Mathieu-Daudé]

The memory region is limited to 1 KiB, so the address is
garantied to be in that range. No need to mask.

  711 static const MemoryRegionOps open_eth_desc_ops = {
  712     .read = open_eth_desc_read,
  713     .write = open_eth_desc_write,
  714 };
  ...
  725     memory_region_init_io(&s->desc_io, OBJECT(dev),
  725                           &open_eth_desc_ops, s,
  726                           "open_eth.desc", 0x400);
