crypto: sahara - remove FLAGS_NEW_KEY logic

Browse source

[ Upstream commit 8fd1834357 ]

Remove the FLAGS_NEW_KEY logic as it has the following issues:
- the wrong key may end up being used when there are multiple data streams:
       t1            t2
    setkey()
    encrypt()
                   setkey()
                   encrypt()

    encrypt() <--- key from t2 is used
- switching between encryption and decryption with the same key is not
  possible, as the hdr flags are only updated when a new setkey() is
  performed

With this change, the key is always sent along with the cryptdata when
performing encryption/decryption operations.
