Fix SR multicast post mfib commit
1 - use the SR policy to construct the replicate DPO. Each bucket therein is a SR tunnel. 2 - install a special mfib entry that links via this replicate 3 - forwarding is now mfib-lookup -> replicate -> sr_rewrite (per-tunnel) no need for a separate sr_replicate node. 4 - Stack the sr tunnel on the forwarding DPO of the first-hop FIB entry. no need for a second lookup post SR encap. 5 - fix some path-list lock leaks in the MFIB entry.
