hs-v3: Don't fetch descriptor if we have a pending request
If 6 SOCKS requests are opened at once, it would have triggered 6 fetches which ultimately poke all 6 HSDir. We don't want that, if we have multiple SOCKS requests for the same service, do one fetch only. Signed-off-by: David Goulet <dgoulet@torproject.org>
