thermal: core: Drop redundant checks from thermal_bind_cdev_to_trip()
Since thermal_bind_cdev_to_trip() is only called by
thermal_zone_cdev_binding() under the thermal zone lock and the latter
is only called by thermal_zone_device_register_with_trips() and
__thermal_cooling_device_register(), under thermal_list_lock in both
cases, both lockdep_assert_held() assertions can be dropped from it.
Moreover, in both cases thermal_zone_cdev_binding() is called after
both tz and cdev have been added to the global lists of thermal zones
and cooling device, respectively, so the check against their list nodes
in thermal_bind_cdev_to_trip() is redundant and can be dropped either.
