From: Arnd Bergmann <arnd@xxxxxxxx>
When the SIMD portion of the driver is disabled, the compiler cannot
figure out in advance if it will be called:
ERROR: modpost: "crypto_aegis128_update_simd" [crypto/aegis128.ko] undefined!
Add a conditional to let the compiler use dead code elimination
as before.
Fixes: ac50aec41a9f ("crypto: aegis128 - expose SIMD code path as separate driver")
