This means that we are now checking multiple times (once on entry for
immediate effect even if migration is under way, and again after
acquiring job condition if migration is not under way), but that
shouldn't hurt.

However, you also need to do the same thing for qemuDomainGetBlockInfo,
since both methods were given the same control flow during commit 18c2a592.
