Dmytro Shynkevych 4369db522b device: wait for routines to stop before removing peers 
Peers are currently removed after Device's goroutines are signaled to stop,
but without waiting for them to actually do so, which is racy.

For example, RoutineHandshake may be in Peer.SendKeepalive
when the corresponding peer is removed, which closes its nonce channel.
This causes a send on a closed channel, as observed in tailscale/tailscale#487.

This patch seems to be the correct synchronizing action:
Peer's goroutines are receivers and handle channel closure gracefully,
so Device's goroutines are the ones that should be fully stopped first.
