Fixes an NPE in OFDPA pipeliners

- Introduced a new method to indicate whether the pipeliner is ready to receive objectives or not
- Ensure init() in OfDpa2Pipeline and OvsOfdpaPipeline can only be invoked once
  This is to avoid processing duplicated DEVICE_ADDED events introduced by gerrit 18899
