From: Saeed Mahameed <sae...@mellanox.com>

mlx5e_get_inline_hdr_size didn't take into account the vlan insertion
into the inline WQE segment.
This could lead to max inline violation in cases where
skb_headlen(skb) + VLAN_HLEN >= sq->max_inline.

Fixes: 3ea4891db8d0 ("net/mlx5e: Fix LSO vlan insertion")
