Using FCP devices with V=V support, the input queue stalled when CCQ 97 had been returned in qdio_do_eqbs. When this happen we have to reissue the eqbs instruction. Another bug was when V=V was enabled we checked if hardware has SIGA-sync support. If not we returned with 0 from tiqdio_is_inbound_q_done. Thus qdio lost initiative on FCP devices and input queue stalled. Running devices in V=V there is no SIGA-sync support but nevertheless we have to process tiqdio_is_inbound_q_done either.
