bugzilla: 175574 https://gitee.com/openeuler/kernel/issues/I4DTUX

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=9beba1469996b5d8d610633c76514a4997bdc763

--------------------------------

[ Upstream commit 5e5c9f9a ]

Zone device is enabled after thermal_zone_of_sensor_register() completion,
but it's not disabled before senor is unregistered, leaving temperature
polling active. This results in accessing a disabled zone device and
produces a warning about this problem. Stop zone device before
unregistering it in order to fix this "use-after-free" problem.
