ip: SVR fix race condition
There could be a race condition where two fragments of one chain end up
at the same time on different workers, one overwriting others hash
entry. Add a check for that and restart processing on the unlucky worker
who ends up being second from hash table POV. This will then result in a
proper handover to worker now owning this reassembly.
Type: fix
