net/mlx5: fix potential memory leak in mlx5e_init_rep_rx 

[ Upstream commit c6cf0b6097 ]

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().
