net/mlx5e: Avoid referencing skb after free-ing in drop path of mlx5e_sq_xmit_wqe
commit 64f14d16eef1f939000f2617b50c7c996b5117d4 upstream.
When SQ is a port timestamping SQ for PTP, do not access tx flags of skb
after free-ing the skb. Free the skb only after all references that depend
on it have been handled in the dropped WQE path.
