[ 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().
