When calling vringh_init_iotlb(), use the negotiated features which
might be different than the supported features.

vdpasim_vq_reset() is called while resetting the device in
vdpasim_reset() where we also set `vdpasim->features = 0` after
resetting the vqs, so maybe it's better to use the supported features
here, since the negotiated ones are related to the previous instance.
Thanks,
Stefano
