Subject: [PATCH] Probabilly defaulting to KTR_GEN is not the right decision
 when KTR_MASK is not defined at all because KTR_GEN is still a valid class
 and some traces may fit in. Default to 0, instead, and block any tracing.

As long as this is a POLA violation (some thirdy-part code, even if
that may be a questionable choice, could be rely on that feature) a
MFC possibility might be carefully evaluated.
