Log:
  g_vfs_open: correctly set devvp.v_bufobj.bo_bsize to DEV_BSIZE
  
  Because of how breadn -> bufstrategy -> g_vfs_strategy are currently
  implemented, bread on devvp always expects DEV_BSIZE block size.
  Thus, devvp bo_bsize must always be DEV_BSIZE irrespective of media
  properties or filesystem implementation details.
