The most obvious is that the feature set was done previous to ACKNOWLEDGE | DRIVER status bit set. Current vdpa devices are permissive with this, but it is better to follow the standard. Apart from that it fixes two issues reported by Peter Maydell: * Stop probing CVQ isolation if cannot set features (goto missed). * Fix incorrect error message statis "error setting features", while it should say status.
