wireguard: add barrier to sync data
The current implmentation of the hash table is not thread-safe.
This design leads to a segfault when VPP is handling a lot of tunnels
for Wireguard, where one thread modifies the hash table and other
threads start the lookup at the same time.
This fix adds a barrier sync to the hash table access when Wireguard
adds or deletes an element.
Type: fix
