[RFC PATCH v3 05/18] dyndbg: hoist ->site out of ddebug_match_site

[Jim Cromie <jim.cromie@gmail.com>]

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
