net.connect: crashes when custom lookup returns invalid address type

[targos]

Test case:

require('net').connect({host: 'localhost', port: 80, lookup: (_, __, cb) => cb(null, '127.0.0.1', 100)});

> require('net').connect({host: 'localhost', port: 80, lookup: (_, __, cb) => cb(null, '127.0.0.1', 100)})
