qemuProcessLaunch: Return earlier if spawning qemu failed
If spawning qemu fails then we report an error and proceed to writing status XML onto the disk. This is unnecessary as we are sure that the domain is not running. At the same time, if virPidFileReadPath() fails it returns -errno. Use it in the error message. It may explain what went wrong.
