sema-svc: execute CE-class work on host-injected compute pushes (the DtoH copy)
cuMemcpyDtoH submits the copy as C5B5 methods bound on subchannel 0 of a
compute channel (eng=0). allow_ops was false for every eng=0 channel, so the
LAUNCH_DMA copy was decoded (and its release applied) but never executed, and
the client read zeros. A host-injected translation is verified truth: allow
CE work on those pushes too.
