[PATCH v2 2/3] transport-helper: run do_take_over in connect_helper

[Jiang Xin <worldhello.net@gmail.com>]

From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

After successfully connecting to the smart transport by calling
"process_connect_service()" in "connect_helper()", run "do_take_over()"
to replace the old vtable with a new one which has methods ready for
the smart transport connection.

The subsequent commit introduces remote archive for a stateless-rpc
connection. But without running "do_take_over()", it may fail to call
"transport_disconnect()" in "run_remote_archiver()" of
"builtin/archive.c". This is because for a stateless connection or a
service like "git-upload-pack-archive", the remote helper may receive a
SIGPIPE signal and exit early. To have a graceful disconnect method by
calling "do_take_over()" will solve this issue.
