Subject: xen: Initialize variable before using

xen: Initialize variable before using

Commit 87b4c10c6cf02251dd8c29b5b895bebc6ec297f9 added code that may call
the virCapabilitiesClearHostNUMACellCPUTopology function with
uninitialized second argument. Although the value wouldn't be used some
compilers whine about that.
