Since the STOP event handler can use the pausedReason as sent to
qemuProcessStopCPUs, we no longer need to send duplicate suspended
lifecycle events because we know what caused the stop along with extra
details. This processing allows us to also remove the duplicated state
change from qemuProcessStopCPUs.

So with these changes how do we handle this special case? See commit
f569b87f5 when this was introduced.
Do we need to adjust qemuProcessHandleStop to not generate the event
when "reason == VIR_DOMAIN_PAUSED_SNAPSHOT && priv->job.asyncJob ==
QEMU_ASYNC_JOB_SNAPSHOT"?
The rest is OK - just need your thoughts on this particular case for the
R-By.
