Remove obsolete workaround from dirserv_thinks_router_is_hs_dir()
There is this comment and code in dirserv_thinks_router_is_hs_dir()
that can safely be removed now that tor-0.2.x is deprecated, right?
/* XXX We shouldn't need to check dir_port, but we do because of
* bug 1693. In the future, once relays set wants_to_be_hs_dir
* correctly, we can revert to only checking dir_port if router's
* version is too old. */
/* XXX Unfortunately, we need to keep checking dir_port until all
* *clients* suffering from bug 2722 are obsolete. The first version
* to fix the bug was 0.2.2.25-alpha. */
return (router->wants_to_be_hs_dir && router->dir_port &&
uptime >= get_options()->MinUptimeHidServDirectoryV2 &&
router_is_active(router, node, now));
