◆ doClose()

performs Transport specific operations to close the transport

This is invoked once by close() after changing state to CLOSING. It will not be invoked by Transport class if the transport is already CLOSING or CLOSED.

When the cleanup procedure is complete, this method should change state to CLOSED. This transition can happen synchronously or asynchronously.

Implements nfd::face::Transport.
