drm/i915/gvt: Use fence error from GVT request for workload status
The req->fence.error will be set if this request caused GPU hang so
we can use this value to workload->status to indicate whether this
GVT request caused any problem. If it caused GPU hang, we shouldn't
trigger any context switch back to the guest.
v2:
- only take -EIO from fence->error. (Zhenyu)
