[PATCH v6 3/4] thermal/drivers/exynos: Remove redundant IS_ERR() checks for clk_sec clock

[Anand Moon]

Remove unnecessary IS_ERR() checks for the clk_sec clock,
the clk_enable() and clk_disable() functions can handle NULL clock
pointers, so the additional checks are redundant and have been removed
to simplify the code.
