[SRU K/J/F/B][PATCH 0/1] Fix regression introduced by CVE-2023-0461 fix

[Stefan Bader]

The fix for the CVE pulled in a code snippet which uses some error
variable which is pre-set to -EADDRINUSE. Some backports drop the
assignment, others don't. But in either way this causes issues because
after passing the new check, err is 0 but later on a failing call to
get_port() needs the pre-assignment because it returns 0/1 and not an
errno.

The submitted patch applies to K/J directly and needs some context
adjustments in F/B.
