drivers/crypto: fix different auth/cipher keys

When ciphering and authenticating in the same operation
(cipher-then-auth or auth-then-cipher),
the cipher key and authentication key were set with the same
key, in SNOW3G, KASUMI and ZUC PMDs.
They were using the key of the first transform structure,
instead of using the keys of the two different transform
structures.

This is not a big issue, since usually, the same key is
used for ciphering and authentication, but keys may be different.
