I think any interface configured with ifconfig_* in rc.conf will cause
an explicit additional "ifconfig up" call from /etc/network.subr.

Furthermore, ifconfig itself will add "up" when setting the IP address.

So, don't configure the carp interface in rc.conf, but do it in
/etc/rc.local, and be careful to add the address while the vhid is not
yet configured, as in:

  ifconfig carp0 create
  ifconfig carp0 inet 192.168.107.21
  ifconfig carp0 down
  ifconfig carp0 vhid 21 pass secret advskew 100

HTH,
Daniel
