[PATCH 4/6] crypto/openssl: fix 3DES-CTR with big endian CPUs

[David Marchand]

Caught by code review.

Don't byte swap unconditionally (assuming that CPU is little endian is
wrong). Instead, convert from big endian to cpu and vice versa.

Fixes: d61f70b4c918 ("crypto/libcrypto: add driver for OpenSSL library")
