Subject: [PATCH] whois: guard against a null activator

whois_event::run_() dereferenced m_activator unconditionally in every
branch (this predates this PR). getvalues_event::run_() and
putvalues_event::run_() already guard the same way elsewhere in this
file; whois_event was missing it. Single early return covers every
branch, old and new.
