Avoid unnecessary work in transportDemuxer.deliverPacket().
- Don't allocate []*endpointsByNic in transportDemuxer.deliverPacket() unless actually needed for UDP broadcast/multicast. - Don't allocate []*endpointsByNic via transportDemuxer.findEndpointLocked() => transportDemuxer.findAllEndpointsLocked(). - Skip unnecessary map lookups in transportDemuxer.findEndpointLocked() => transportDemuxer.findAllEndpointsLocked() (now iterEndpointsLocked). For most deliverable packets other than UDP broadcast/multicast packets, this saves two slice allocations and three map lookups per packet. PiperOrigin-RevId: 300804135
