In below code flow, for ingress acl table root ns memory leads
to double free.
mlx5_init_fs
init_ingress_acls_root_ns()
init_ingress_acl_root_ns
kfree(steering->esw_ingress_root_ns);
/* steering->esw_ingress_root_ns is not marked NULL */
mlx5_cleanup_fs
cleanup_ingress_acls_root_ns
steering->esw_ingress_root_ns non NULL check passes.
kfree(steering->esw_ingress_root_ns);
/* double free */
Similar issue exist for other tables.
Hence zero out the pointers to not process the table again.
Fixes: 9b93ab981e3bf ("net/mlx5: Separate ingress/egress namespaces for each vport")
Fixes: 40c3eebb49e51 ("net/mlx5: Add support in RDMA RX steering")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
