https://bugzilla.redhat.com/show_bug.cgi?id=1197600 when create a happy vm and then restart libvirtd, we will loss priv->pidfile, because we don't check if it is there is a pidfile. However we only use this pidfile when we start the vm, and won't use it after it start, so this is not a big deal. But it is strange when vm is offline but pidfile still exist, so remove vmname.pid in state dir (maybe /run/libvirt/qemu/)when priv->pidfile is NULL.
