Please, put separate cases by an empty line. It's pretty hard to read
such a big block of uppercase latters.

I'm afraid this could be reported as unreachable code by some picky
static analyzers, so how about:

    switch (status) {
    case QEMU_DOMAIN_JOB_STATUS_NONE:
        break;

    ...
    }

    return VIR_DOMAIN_JOB_NONE;

I think it would make sense to rename this function as
qemuMigrationUpdateJobStatus in a follow-up patch.

ACK with the cosmetic changes.
