net/mlx5: Fix rtable reference leak
[ Upstream commit 2347cee83b2bd868bde2d283db0fac89f22be4e0 ]
If the rt entry gateway family is not AF_INET for multipath device,
rtable reference is leaked.
Hence, fix it by releasing the reference.
Fixes: 5fb091e8130b ("net/mlx5e: Use hint to resolve route when in HW multipath mode")
Fixes: e32ee6c78efa ("net/mlx5e: Support tunnel encap over tagged Ethernet")
