crypto: ccp - Fix 3DES complaint from ccp-crypto module
Crypto self-tests reveal an error:
alg: skcipher: cbc-des3-ccp encryption test failed (wrong output IV) on test vector 0, cfg="in-place"
The offset value should not be recomputed when retrieving the context.
Also, a code path exists which makes decisions based on older (version 3)
hardware; a v3 device deosn't support 3DES so remove this check.
