Net: processUnblockedClients() and clientsArePaused() minor changes.

1. No need to set btype in processUnblockedClients(), since clients
   flagged REDIS_UNBLOCKED should have it already cleared.
2. When putting clients in the unblocked clients list, clientsArePaused()
   should flag them with REDIS_UNBLOCKED. Not strictly needed with the
   current code but is more coherent.
