crypto: x86/sha256 - fix possible crash with CFI enabled

sha256_transform_ssse3(), sha256_transform_avx(),
sha256_transform_rorx(), and sha256_ni_transform() 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")
