OSPF v3 DR - intra-area-prefix LSA generation

[Bala Sajja]

I am running bird 2.0.7. Seeing issue with respect to ipv6 address
add/delete on DR. This added/deleted ipv6 address prefix convergence is not
happening  till LSA refresh timer fires .

Topology contains  3 routers connected to a switch. Say IPV6 addresses
configured on Routers R1(1111::100/64), R2(2222:200/64),R3(3333::300/64).

If we are deleting ipv6 addresses other than DR, I could see
intra-area-prefix generated by DR and all routers converged with respect to
add/deleted ipv6 addresses.

With the below change, I could see intra-area-prefix LSA generated on DR
also when ipv6 address added/deleted on DR.  Please advise if this fix
is  correct ?

   }
