pw_transfer: Properly clean up after completion

- Set the transfer state to kCompleted when a client transfer completes.
- When searching for a context to use in the client, only return an
  error of finding the same transfer ID if the transfer is active.
- Use ALREADY_EXISTS when attempting to start a transfer ID that's
  already pending since it's more specific.
