wireguard: fix potential leaks of async frame

The current implementation can cause memory leaks of async frames
and exhaust the async frames pool. Wireguard can early get async frame,
even when later it turns out it is not needed. Then such frame won't
be freed.

This fix changes the moment of acquiring async frame from the pool, so
it doesn't leak.

Type: fix
