MEDIUM: backend: Defer conn_xprt_start() after mux creation

Browse Source 
In connect_server(), defer the call to conn_xprt_start() until after we
had a chance to create the mux. The xprt can behave differently
depending on if a mux is or is not available at this point, as if it is,
it may want to wait until some data comes from the mux.

This does not need to be backported.
