[PATCH 11/12] mesh: Send peering open frame again if beacon from listen state peer is received

I think I need to consider more about this.

So I will drop this patch from the patch set for now.

As thomas said, to use scan result is reasonable way (thanks thomas).
Because the sequence scan -> find peer -> connect -> timeout -> scan -> ... is
similar to infrastructure BSS.
If NEW_PEER_CANDIDATE based connection trigger can not avoid this issue,
I will consider scan based.
