crypto: x86/aria - fix crash with CFI enabled

aria_aesni_avx_encrypt_16way(), aria_aesni_avx_decrypt_16way(),
aria_aesni_avx_ctr_crypt_16way(), aria_aesni_avx_gfni_encrypt_16way(),
aria_aesni_avx_gfni_decrypt_16way(), and
aria_aesni_avx_gfni_ctr_crypt_16way() are called via indirect function
calls.  Therefore they need to use SYM_TYPED_FUNC_START instead of
SYM_FUNC_START to cause their type hashes to be emitted when the kernel
is built with CONFIG_CFI_CLANG=y.  Otherwise, the code crashes with a
CFI failure.

Fixes: ccace936eec7 ("x86: Add types to indirectly called assembly functions")
