Subject: [RFC PATCH v5 07/28] dyndbg: hoist ->site out of ddebug_match_site
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
