Title: small cleanup: stale comment, remove confusing log message

Removes a stale comment, and a log message we currently emit about "shutting down ngx_pagespeed root".

This message is also written when pagespeed is never enabled in nginx.conf, as we will clean up and shutdown the rewrite driver factory in that case.
