[libvirt] [PATCH 04/10] Fix crash on OOM in qemuDomainCCWAddressSetCreate()

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

If OOM occurs in qemuDomainCCWAddressSetCreate, it jumps to
a cleanup block and frees the partially initialized object.
It then mistakenly returns the address of the just free'd
pointer instead of NULL.
