libvhost-user: Zero memory allocated for VuVirtqInflightDesc
Use a zero-initialized VuVirtqInflightDesc struct to avoid
that scan-build reports that vq->resubmit_list[0].counter may
be garbage value in vu_check_queue_inflights().
Fixes: 5f9ff1eff ("libvhost-user: Support tracking inflight I/O in
shared memory")
