Reorder section 2 of deployment/docker-swarm.md

The current ordering implies to users that they are able to deploy the samples before
it is explained that it may take a (small) period of time for the OF stack to download
and initialise.

This change moves the instruction to deploy the sample functions after the explanation
that deploying the stack may take time and means that the user will not try to deploy
the sample functions until they have seen the ui, guaranteeing that the gateway is ready.
