net/mlx5e: Don't support encap rules with gbp option
[ Upstream commit d515d63cae2cd186acf40deaa8ef33067bb7f637 ]
Previously, encap rules with gbp option would be offloaded by mistake but
driver does not support gbp option offload.
To fix this issue, check if the encap rule has gbp option and don't
offload the rule
