crypto: x86/aegis128 - fix possible crash with CFI enabled
crypto_aegis128_aesni_enc(), crypto_aegis128_aesni_enc_tail(),
crypto_aegis128_aesni_dec(), and crypto_aegis128_aesni_dec_tail() 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 (if the compiler didn't
happen to optimize out the indirect calls).
Fixes: ccace936eec7 ("x86: Add types to indirectly called assembly functions")
