Subject: [PATCH 6/6] kconfig: pass new the conf_changed value to the callback

Commit ee06a3ef7e3c ("kconfig: Update config changed flag before calling
callback") pointed out that conf_updated flag must be updated before
calling the callback because it needs to know the new value.

If so, it makes sense to pass the new value to the callback.
