mlxsw: spectrum_router: Relax GRE decap matching check
GRE decap offload is configured when local routes prefix correspond to the local address of one of the offloaded GRE tunnels. The matching check was found to be too strict, such that for a flat GRE configuration, in which the overlay and underlay traffic share the same non-default VRF, decap flow was not offloaded. Relax the check for decap flow offloading. A match occurs if the local address of the tunnel matches the local route address while both share the same VRF table.
