[PATCH v4 2/4] transport-helper: call do_take_over() in process_connect

[Jiang Xin <worldhello.net@xxxxxxxxx>]

From: Jiang Xin <zhiyou.jx@xxxxxxxxxxxxxxx>

The existing pattern among all callers of process_connect() seems to be

        if (process_connect(...)) {
                do_take_over();
                ... dispatch to the underlying method ...
        }
        ... otherwise implement the fallback ...

where the return value from process_connect() is the return value of the
call it makes to process_connect_service().

Move the call of do_take_over() inside process_connect(), so that
calling the process_connect() function is more concise and will not
miss do_take_over().
