crypto: s5p-sss - Add error handling in s5p_aes_probe()
commit a472cc0dde3eb057db71c80f102556eeced03805 upstream.
The function s5p_aes_probe() does not perform sufficient error
checking after executing platform_get_resource(), thus fix it.
Fixes: c2afad6c6105 ("crypto: s5p-sss - Add HASH support for Exynos")
