Description
In https://github.com/libp2p/go-libp2p-swarm/pull/227, it's possible for a dial to be initiated on a transport after calling `Close` while shutting down. This _usually_ won't be an issue, but it would be nice to make this situation impossible.

Research direction
Start by reviewing the shutdown and dialing behavior discussed in pull request #227, focusing on how transports are selected after Close is called. Trace the interaction between Close and an in-progress dial, then verify that no transport is used after shutdown begins, including during concurrent shutdown and dialing.
