Subject: [net V2 2/9] net/mlx5e: fix memory leak in mlx5e_fs_tt_redirect_any_create
From: Zhengchao Shao <shaozhengchao@...wei.com>
The memory pointed to by the fs->any pointer is not freed in the error
path of mlx5e_fs_tt_redirect_any_create, which can lead to a memory leak.
Fix by freeing the memory in the error path, thereby making the error path
identical to mlx5e_fs_tt_redirect_any_destroy().
Fixes: 0f575c20bf06 ("net/mlx5e: Introduce Flow Steering ANY API")
