Description (partial)

Symptom:The router doesn't apply correct cost to inter-area router LSA (Type 4), when OSPFv3 Max-Metric is configured.
There is a mem leak also in function ospfv3_send_iartr_lsa. when we generate the inter area router LSA.

Conditions:On platforms with x86 processors, the metric of type-4 LSAs doesn't change upon entering or leaving max-metric mode.

On platforms with ppc processors, the metric is changing, but not to the desired value for type-3 and type-4 LSAs.

when we are sending the inter area router LSA via function ospfv3_send_iartr_lsa we first looks into the database to get the LSA. but the dest router ID which we passed does not convert in to host order. due to that we will not find LSA in the database. later when we again do a search we passed the converted dest rtr ID and see the LSA in DB. 
due to that we are leaking memory
