wireguard: add atomic mutex
The initiate handshake process can be called a numbers times for each
peers, then the main VPP thread called by Wireguard starting to
allocate memory. This behaviour can lead to out of memory when VPP has
a lot of Wireguard tunnels concurrently.
This fix add mutex to send only once handshake initiate at time for
each peers.
Type: fix
