[libvirt] [PATCH] qemudDomainMigrateFinish2: handle a case of virDomainSaveStatus failure

[Jim Meyering]

This is very similar to ones I fixed yesterday.
The difference is that I'm adding ATTRIBUTE_RETURN_CHECK, now.
Here, it's easy, since the function is private.

Subject: [PATCH] qemudDomainMigrateFinish2: handle a case of virDomainSaveStatus failure

* src/qemu/qemu_driver.c (qemudDomainMigrateFinish2): Don't ignore
virDomainSaveStatus failure.
* src/conf/domain_conf.h (virDomainSaveStatus): Use
ATTRIBUTE_RETURN_CHECK, so this doesn't happen again.
