async_hooks: avoid double-destroy HTTPParser
Avoid that destroy hook is invoked twice - once via `Parser::Free()` and once again via `Parser::Reinitialize()` by clearing the async_id in `EmitDestroy()`. Partial backport of nodejs#27477, a full backport would require also nodejs#25094 which has a dont-land-on-v10.x label on it. Fixes: nodejs#26961
