zebra: send RA lifetime of 0 before ceasing to advertise RAs
Problem reported by testing agency that RFC4861 section 6.2.5
states that a router should send an RA with a lifetime of 0
before ceasing to send RAs on the interface, or when the interace
is shutdown, or the router is shutdown. This fix adds that capability.
Ticket: CM-27061
