[libvirt] [PATCH] examples: Initialize @pos in domtop.c

[Martin Kletzander]

This is a zero-cost workaround for a bug in GCC 8.3.0 which causes the
compilation to fail, because the compiler thinks that the value might be used
uninitialized even though it clearly cannot be.

This is technically a fix for a build-breaker, but I'm sending it for review as
it is not that big of a deal it being in examples/
