crypto: x86/sha512-avx2 - add missing vzeroupper
Since sha512_transform_rorx() uses ymm registers, execute vzeroupper
before returning from it. This is necessary to avoid reducing the
performance of SSE code.
Fixes: e01d69cb0195 ("crypto: sha512 - Optimized SHA512 x86_64 assembly routine using AVX instructions.")
