Jet verification flags are broken.

[sigilante]

When running a jet which returns u3_none, the jet verification flags do not fall through back to "correct".

static u3j_harm _139_non__lagoon_add_a[]  = {{".2", u3wi_la_add, c3n}, {}};

will fail on return u3_none;, while

static u3j_harm _139_non__lagoon_add_a[]  = {{".2", u3wi_la_add}, {}};

will (correctly) successfully fall through to the Hoon on u3_none.
