[PATCH v5 2/3] drivers/thermal/exymos: Remove redundant IS_ERR() checks for clk_sec clock

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.
