g_vfs_open: correctly set devvp.v_bufobj.bo_bsize to DEV_BSIZE

Browse Source 
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.
