zebra: remove unused zevpn_lookup() declaration

[iurmanj6WIND]

Remove unused zevpn_lookup() declaration in zebra_vxlan_private.h.

[greptile-apps]

Greptile Summary

This PR removes the orphaned extern struct zebra_evpn *zevpn_lookup(vni_t vni) declaration from zebra/zebra_vxlan_private.h. A grep across the entire repository confirms no definition or call site for this symbol exists anywhere in the tree, making the removal safe.

• Removes one stale header declaration that had no corresponding definition or caller anywhere in the codebase.

Confidence Score: 5/5

Removing a single dead extern declaration with no definition and no callers anywhere in the tree is a no-risk cleanup.

The deleted line is a forward declaration that has no matching definition and is never referenced. The grep across the full repository found zero occurrences after the removal, so nothing breaks.

No files require special attention.
