A failure in qemuProcessLaunch would lead to qemuExtDevicesStop
b971b8
being called twice - once in the cleanup section and then again
b971b8
in qemuProcessStop.

b971b8

b971b8
the swtmp_ioctl command can lock up:

Remove the first call and only leave the one in qemuProcessStop,
b971b8
which is called after the QEMU process is killed.
