ospfd: update ospf_asbr_status when using no_area_nssa command

Browse source 
In the processing of nssa, if the number of areas that need to be translated is greater than 0, then abr will be regarded as asbr, and it will be marked (0x3) in the flag of router lsa. When a certain area is set from nssa to a normal area, the areas that need to be translated may be reduced. The asbr should be re-interpreted as abr when the translated area is 0.
