    bhyve/virtio: check negotiated_caps for indirect descriptor support
    
    vq_getchain() erroneously checked vc_hv_caps for indirect descriptor
    support when it encountered an indirect descriptor. vc_hv_caps is used
    in feature negotiation to advertise what features our device emulation
    supports, but we should really check what features we have negotiated
    with the driver.
