Faster circuit_get_by_rend_token_and_purpose()

On busy servers, this function takes up something like 3-7% in
different profiles, and gets invoked every time we need to participate
as the midpoint in a hidden service.

So maybe walking through a linked list of all the circuits here wasn't
a good idea.
