net/mlx5: fix potential memory leak in mlx5e_init_rep_rx
[ Upstream commit c6cf0b6097bf1bf1b2a89b521e9ecd26b581a93a ]
The memory pointed to by the priv->rx_res pointer is not freed in the error
path of mlx5e_init_rep_rx, which can lead to a memory leak. Fix by freeing
the memory in the error path, thereby making the error path identical to
mlx5e_cleanup_rep_rx().
Fixes: af8bbf730068 ("net/mlx5e: Convert mlx5e_flow_steering member of mlx5e_priv to pointer")
