[tor/maint-0.3.3] Fix memory leak in pick_hsdir_v3().
by nickm＠torproject.org 29 Jun '18

commit ce5d055ed7e4d8e5d1c0b0b922738c87b6a8da1c Author: Alexander Færøy <ahf(a)torproject.org> Date: Sat Jun 23 03:40:32 2018 +0200 Fix memory leak in pick_hsdir_v3(). This patch fixes a memory leak in pick_hsdir_v3() where we might return early, but forgot to free the responsible_hsdirs variable. We solve this by not allocating storage for responsible_hsdirs until it's actually needed.
