* ospf_interface.c: (ospf_if_table_lookup) Fix a serious bug
a less serious one.
1: this function is supposed to lookup
entries in the oifs ospf_interface route_table and return either
an existing oi or NULL to indicate not found, its caller depends
on this, yet this function uses route_node_get which /always/
returns a route_node - one is created if none exists. Use
route_node_lookup instead. This should fix root cause of the
reports of the (ospf_add_to_if) assert being hit.
2: oi's are inserted into this table with prefixlength set to
/32 (indeed, it should be a hash table, not a route_table),
however prefixlength to lookup was not changed, if no valid entry
can be inserted other than /32, then nothng but /32 should be
looked up. This possibly only worked by fluke..
Fix confirmed by 2 reporters (one list, one IRC), definitely a
backport candidate once it has been incubated in HEAD for a while.
Thanks to Patrick Friedel and Ivan Warren for testing.
