MEDIUM: backend: move the connection finalization step to back_handle_st_con()

Currently there's still lots of code in conn_complete_server() that performs
one half of the connection setup, which is then checked and finalized in
back_handle_st_con(). There isn't a valid reason for this anymore, we can
simplify this and make sure that conn_complete_server() only wakes the stream
up to inform it about the fact the whole connection stack is set up so that
back_handle_st_con() finishes its job at the stream-int level.

It looks like the there could even be further simplified, but for now it
was moved straight out of conn_complete_server() with no modification.
