Asserting the value we set four lines earlier in qemuBlockjobState doesn't buy us any safety (if the public header adds a value, we end up skipping that value without the compiler warning us of our gap); what we really want is to assert that the value auto-assigned by the compiler matches the actual last value in the public headers (as was done below for qemuBlockJobType). Add useful comments while at it.
