dracut-module-setup.sh: ensure cluster info is ready before query

Browse Source 
There is a race issue between "pcs" and "kdumpctl restart"

-1. set up cluster
 # pcs cluster setup --start mycluster node1 node2
 # pcs stonith create kdump fence_kdump pcmk_reboot_action="off"
 # pcs stonith level add 1 node1 kdump
 # pcs stonith level add 1 node2 kdump

-2. Then here comes the command _immediately_ in kdumpctl
 # pcs cluster cib

But due to some pcs internal mechanism, "pcs cluster cib" can not
fetch the updated info in time.

Fix these issue by forcing the upgrade of cib.
