ospf6d: fix flushing of all LSAs when NSSA is unconfigured

Browse Source 
Once NSSA is unconfigured on an area, all self-originated Type-7
LSAs need to be flushed. The existing code was iterating over the
LSDB in the wrong way, causing ospf6_nssa_flush_area() to flush
LSAs of all types.  Use the ALL_LSDB_TYPED_ADVRTR macro to perform
the intended iteration correctly.
