[libvirt] [PATCH 1/2] qemu: Acquire domain job in qemuDomainGetFSInfo and qemuDomainGetGuestInfo

[Michal Privoznik]

These two functions work with vm->def in their critical sections
(i.e. after the job was acquired and before it is released). But
that means, they need QUERY domain job too to prevent vm->def
change.
