ospf6d: Fix memory allocation issues in SPF
* ospf6_area.c: Call ospf6_spf_table_finish() before deleting the spf
table. This ensures that the associated ospf6_vertex structures
are also freed.
* ospf6_spf.c: Only allocate a priority queue when a spf calculation
is actually performed. Also defer calling ospf6_spf_table_finish().
