Subject: [net 2/9] net/mlx5e: fix memory leak in mlx5e_fs_tt_redirect_any_create

From: Zhengchao Shao <[email-masked]>

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")
