commit 5e19cc2c1bf22d introduced a workaround for a race condition
that showed itself on IPv6 ifconfig on FreeBSD 12.x - sometimes breaking
IPv6 connectivity on tun/tap interfaces.
This was fixed on the FreeBSD side in 12.4, 13.1 and up, and 13.0 is
no longer supported. So conditionalize the workaround on "12.0..12.3",
to be fully removed later when 12.3 is also running out of support.
