[libvirt] [PATCH 1/3] qemuProcessStop: Set @def early

The @def variable holds pointer to the domain defintion, but is set only somewhere in the middle of the function. This is suboptimal.

Maybe even less confusing - how about initializing it during the variable declaration at the very beginning of the function? Reviewed-by: Erik Skultety <eskultet@redhat.com>
