* gh-128916: Do not set `SO_REUSEPORT` on non-`AF_INET*` sockets

Do not attempt to set ``SO_REUSEPORT`` on sockets of address familifies other
than ``AF_INET`` and ``AF_INET6``, as it is meaningless with these address
families, and the call with fail with Linux kernel 6.12.9 and newer.

* Apply suggestions from code review
