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.
