Ovidiu Panait 8fd1834357 crypto: sahara - remove FLAGS_NEW_KEY logic
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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
