net/mlx5e: use %pad format string for dma_addr_t

On 32-bit ARM with 64-bit dma_addr_t I get this warning about an
incorrect format string:

In file included from /git/arm-soc/drivers/net/ethernet/mellanox/mlx5/core/alloc.c:42:0:
drivers/net/ethernet/mellanox/mlx5/core/alloc.c: In function ‘mlx5_frag_buf_alloc_node’:
drivers/net/ethernet/mellanox/mlx5/core/alloc.c:134:12: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]

We have the special %pad format for printing dma_addr_t, so use that
to print the correct address and avoid the warning.
