pfctl Recursive in anchor broken(DIOCGETRULES: Invalid argument)?

uname -a
FreeBSD 11.2-RELEASE FreeBSD 11.2-RELEASE #0 r335510: Fri Jun 22 04:32:14

 amd64

I know that 11.2-R is EOL and I have run freebsd-update to upgrade to
12.1，but have not reboot,so the new kernel is not take effect.

freebsd-version -ku
12.1-RELEASE-p1
11.2-RELEASE-p2
