Pass empty string instead of NULL to ns_client_dumpmessage()

The two new call sites added by the CLASS-validation work passed NULL
as the reason, but ns_client_dumpmessage() bails out early on a NULL
reason — so the message dump never happened. The intent was to dump
the message and let the follow-up ns_client_log() carry the reason
text, so pass "" to suppress the prefix without short-circuiting the
dump.
