Subject: drivers/thermal/exynos_thermal.c: fix NULL pointer dereference in exynos_unregister_thermal()
exynos_unregister_thermal() is functional only when 'th_zone' is not NULL
(ensured by the NULL checks). However, in the event it is NULL, it gets
dereferenced in the for loop. This patch fixes this issue.
