Long-distance bonded interaction issue with CUDA and domain decomposition - Redmine #3063

Forces could be missing for bonded interactions computed on CUDA GPUs with domain decomposition when there are non-local bonded interactions, but no non-local non-bonded interactions between two domains. Note that this is extremely unlikely to happen, since the distance between the bonded atoms needs to be larger than the pair list cut-off distance and there should be no other non-local atoms within the cut-off distance.
