Afterd12e1c4649("net: dsa: b53: Set correct number of ports in the DSA struct") we stopped setting dsa_switch::num_ports to DSA_MAX_PORTS, which created an off by one error between the statically allocated bcm_sf2_priv::port_sts array (of size DSA_MAX_PORTS). When dsa_is_cpu_port() is used, we end-up accessing an out of bounds member and causing a NPD. Fix this by iterating with the appropriate port count using ds->num_ports.

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.
