[libvirt] [PATCH] qemu: Take error path if acquiring of job fails in qemuDomainSaveInternal

[Peter Krempa]

Due to a goto statement missed when refactoring in 2771f8b74c1bf50d1fa
when acquiring of a domain job failed the error path was not taken. This
resulted into a crash afterwards as a extra reference was removed from a
domain object leading to it being freed. An attempt to list the domains
afterwards leaded to a crash of the daemon afterwards.

Sorry for breaking that in the first place :/
