This will leave the entry without unlocking it, thus having the inuse counter
increased and never decreased again. It will never get pruned.

I believe a better fix is to make the unlock (unconditionally like it is
currently made in Curl_done()) in the Curl_disconnect() function. We want the
inuse counter to be zero when nothing uses the dns entry anymore.

I think your extra lock calls are fine so we should update 506 once we've
completed this fix.
