crypto: blowfish - disable AVX2 implementation
It appears that the performance of 'vpgatherdd' is suboptimal for this kind of workload (tested on Core i5-4570) and causes blowfish-avx2 to be significantly slower than blowfish-amd64. So disable the AVX2 implementation to avoid performance regressions. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
