The current code was still triggering an assertion in if_delmulti() due to the parent interface being partially detached. Fix this by not calling if_delmulti() at all if the parent interface is being detached. Warn if if_delmulti() fails when the parent is not being detached (but similar to 208212, still proceed with tearing down the vlan state). END
