Node.js: avoided use of request struct for debug logging.

This fixes a crash on exit of Node.js application.  The crash reproduced
on Ubuntu 20.10 with Node.js v15.1.0.  Tests 'test_node_websockets_two_clients'
and 'test_node_websockets_7_13_1__7_13_2'.

The reason of the crash is using request struct which was already freed.

The issue was introduced in 5be509fda29e.
