do notice-level log when we resume having enough dir info

we do a notice-level log when we decide we *don't* have enough dir info, but in 0.3.5.1-alpha (see commit eee62e13d97, #14950) we lost our corresponding notice-level log when things come back.

bugfix on 0.3.5.1-alpha; fixes bug 40496. --- changes/bug40496 | 6 ++++++ src/feature/nodelist/nodelist.c | 10 ++++++++-- 2 files changed, 14 insertions(+), 2 deletions(-)
