cpufreq: exynos: Initialize return variable

'ret' is undefined when the function returns from the first
'if' condition. Without this patch we get the following warning:

drivers/cpufreq/exynos-cpufreq.c: In function 'exynos_target':
drivers/cpufreq/exynos-cpufreq.c:182:2: warning: 'ret' may be used uninitialized in this function [-Wuninitialized]
