Subject: [PATCH] CURLMOPT_SOCKETFUNCTION.md: fix the callback argument use

The example code does not use curl_multi_assign(), but its callback
function used socketp (called sockp in the function) to get the struct
priv pointer instead of the correct clientp (cbp).

Reported-by: Greg Hudson
Fixes #19840
Closes #19841
