Eric Dumazet 3608b13ccc mlx4: reduce OOM risk on arches with large pages
Since mlx4 NIC are used on PowerPC with 64K pages, we need to adapt
MLX4_EN_ALLOC_PREFER_ORDER definition.

Otherwise, a fragment sitting in an out of order TCP queue can hold
0.5 Mbytes and it is a serious OOM risk.

Fixes: 51151a16a6 ("mlx4: allow order-0 memory allocations in RX path")
