ospfd: Ospf ABR doesnt Advertise LSA summary

Browse Source 
Description:
	OSPF ABR will summarise the networks based on configured range
	and re-advtertise the summarised route. But if configured range
	prefix id is same as one of the subset of routes prefix id then
	as per rcf2328 Appendex-E recommendation, it will prepare the LSID and originate.
	While re-advertising, it is using ospf LSDB instead of area specific
	LSDB which is making it fail to re-advertise the summary lsa.
	Fixed this by passing correct LSDB pointer.

Issue: #12995
