[libvirt] [PATCH] Fix check of virKillProcess return status

[Daniel P. Berrange]

The error code for virKillProcess is returned in the errno variable
not the return value. THis mistake caused the logs to be filled with
errors when shutting down QEMU processes

* src/qemu/qemu_process.c: Fix process kill check.
