qemu: Pass stop reason from qemuProcessStopCPUs to stop handler

Browse Source 
Similar to commit [1] which saves and passes the running reason to
the RESUME event handler, during qemuProcessStopCPUs let's save and pass
the pause reason in the domain private data so that the STOP event
handler can use it.
