ospf6d: always remove the result of a previous SPF calculation

This is needed to avoid stale routes in some cases; the regression was
introduced by commit 1d19234e79c77a7d55194b513f2a77c6a691bc2c.

* ospf6_spf.c: (ospf6_spf_calculation) Call ospf6_spf_table_finish()
  before possibly returning if no router-LSA is found for the root of
  the SPF tree.
