[PATCH v2] thermal: exynos: fix masking value for exynos7 temp_error

[Sang Min Kim]

Modify mask value for the temp_error in the sanitize_temp_error() function.
 
Fixes: aef27b658b43 ("thermal: exynos: use sanitize_temp_error() in exynos7_tmu_initialize()")
masked temp_error2 with EXYNOS_TMU_TEMP_MASK(0xff) value even in the case
of EXYNOS7.
In addition, when entering the if statement, both temp_error1 and 2 are
masked with EXYNOS_TMU_TEMP_MASK(0xff).
 
By modifying to use the previously declared local variable tmu_temp_mask,
the mask value suitable for the SOC can be applied.
