net/mlx5e: Don't support encap rules with gbp option

[ Upstream commit 07c8a9238b6e0c36e949d9c7a614a24e37df30a4 ]

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
