[RFC PATCH v6 09/34] dyndbg: hoist ->site out of ddebug_match_site

From: Jim Cromie
Date: Sat May 29 2021 - 16:02:38 EST


A coming change adds _get/_put abstraction on the site pointer, to
allow managing site info more flexibly. The get/put pattern is best
done at a single lexical scope, where its more obviously correct, so
hoist the ->site ref out of ddebug_match_site, and pass it in instead.

no functional changes
