[PATCH] s390: V=V qdio fixes
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.
