thermal: exynos: Propagate error value from tmu_read()

Browse source

commit c8da6cdef5 upstream.

tmu_read() in case of Exynos4210 might return error for out of bound
values. Current code ignores such value, what leads to reporting critical
temperature value. Add proper error code propagation to exynos_get_temp()
function.
