GHash: eliminate one of the lookup_nodes functions.
GHash: eliminate one of the lookup_nodes functions.

Kill g_hash_table_lookup_node and rename g_hash_table_lookup_node_for_insertion
to g_hash_table_lookup_node.  Since at this point we already check for
toombstones in all callers of g_hash_table_lookup_node this doesn't make
a difference.
