net/mlx5e: Fix the max MTU check in case of XDP

MLX5E_XDP_MAX_MTU was calculated incorrectly. It didn't account for
NET_IP_ALIGN and MLX5E_HW2SW_MTU, and it also misused MLX5_SKB_FRAG_SZ.
This commit fixes the calculations and adds a brief explanation for the
formula used.

Fixes: 5d6f6b78b8cf7 ("net/mlx5e: Restrict the combination of large MTU and XDP")
