crypto: x86/sm3 - fix possible crash with CFI enabled
sm3_transform_avx() is called via indirect function calls. Therefore it
needs to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause its
type hash 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 call).
Fixes: ccace936eec7 ("x86: Add types to indirectly called assembly functions")
