drivers: thermal: Exit sysfs notify kthread when sensor unregisters

When a thermal zone unregisters, it initiates a blocking call
kthread_stop for the sysfs notify kthread to exit. But the sysfs notify
kthread is blocked on a completion event, which may not be triggered after
the sensor driver initiates a thermal zone unregister call. So, the
kthread_stop will be blocked forever.

As a part of thermal zone unregister, set a thermal zone unregister flag
and send a completion event before calling kthread_stop. Make the sysfs
notify kthread to be aware of thermal zone unregister flag and exit
after the completion event is triggered.
