net.inet.ip.dummynet.pipe_slot_limit only exists after dummynet is kldloaded, which comes after the sysctls are applied. That order's the same in rc.bootup as it's always been, and that did apply cleanly from tunables in past versions, but something's changed where dummynet isn't loaded where it was before.

Regardless it shouldn't be necessary to manually set that, we can set it automatically to the appropriate maximum value.
