[libvirt] PATCH: don't print uninitialized integer in diagnostic

[Jim Meyering <jim@xxxxxxxxxxxx>]

In adding a test of the vcpu cpuset parsing code (another patch coming
separately), I noticed a bogus diagnostic:

  virsh --connect test:///default dumpxml 1 > xml
  sed "s/vcpu>/vcpu cpuset='aaa'>/" xml > xml-invalid
  ./virsh --connect test:///default define xml-invalid 2>&1 |head -1
  libvir: Domain Config error : failed Xen syscall topology cpuset syntax error -2027441560

With the patch below, I get this output instead:
(i.e., same, but without the trailing negative number)

  $ ./virsh --connect test:///default define xml-invalid 2>&1 |head -1
  libvir: Domain Config error : failed Xen syscall topology cpuset syntax error
