[tor-commits] [tor/master] hs: Set rendezvous circuit timestamp_dirty all the time



commit a52a32c855b2ed59cb915ad687d80f1294c6f0a3

    hs: Set rendezvous circuit timestamp_dirty all the time
    
    We used to check if it was set to 0 which is what unused circuit have but when
    the rendezvous circuit was cannibalized, the timestamp_dirty is not 0 but we
    still need to reset it so we can actually use it without having the chance of
    expiring the next second (or very soon).
    
    Fixes #23123
