ha: Put fs resource before vip one in order/colocation/group

The reason is that we started the fs one earlier on. With the vip
resource first, we would have to stop the fs primitive and then restart
to respect the order (ie, vip starts before fs).

ha: Fix race on creation of drbd resources

The drbd OCF resource agent expects the drbd primitive and the drbd ms
resource to be created in the same transaction. When it doesn't, then
the drbd primitve will fail to be monitored, which can lead to fencing.

We didn't see that all the time because we create the ms resource fast,
so most of the time, it just works.
