    Fix CID 1473233 in handle_control_hsfetch().
    
    With v2 support for HSFETCH gone, we only support v3 addresses. We don't
    support v2 descriptor IDs anymore and hence we can remove that code.
    
    The code removed would ensure that if a v2 descriptor ID was provided, the user
    also had to provide HSDirs explicitly.
    
    In the v3 case, the code should work even if no HSDirs are provided, and Tor
    would find the HSDirs itself.
