[ Upstream commit 3250affdc658557a41df9c5fb567723e421f8bf2 ]
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().
