vgsp-sema r563c: the stall watchdog gates on ACTIVE withheld work, not cumulative counters

r566 evidence: the dump fired 4x with done=8929 and opdef=215/7/5 frozen
while the ring was EMPTY (every channel last_get == put - the clients were
waiting, no entry pending) and the forced flush had nothing to deliver:
 is a lifetime counter (215 holds applied/expired long ago),
not proof of a current hold. A real stall has either a pending translation
(svc_pending_n) or an ACTIVE opdef slot with releases recorded
(e->active && e->n); the dump (and with it the self-heal arm) now requires
one of those. The r564-class true stalls (active slots holding releases)
still dump and still heal.
