thermal: netlink: Pass pointers to thermal_notify_tz_trip_up/down()

Instead of requiring the callers of thermal_notify_tz_trip_up/down() to
provide specific values needed to populate struct param in them, make
them extract those values from objects passed by the callers via const
pointers.

No intentional functional impact.
