[libvirt PATCH 3/3] virQEMUCapsSetHostModel: Fix memory leak

[Tim Wiederhake]

virQEMUCapsSetHostModel is called by virQEMUCapsInitHostCPUModel,
which in turn is typically called twice (for KVM and QEMU), e.g. in
virQEMUCapsLoadCache and virQEMUCapsNewForBinaryInternal.

The second call leaks memory pointed to by "reported", "migratable"
and "full".
