Consumer of the kernel crypto api, after allocating
the transformation, sets this flag based on the basis
of the type of key consumer has. This helps:

- This helps to influence the core processing logic
  for the encapsulated algorithm.
- This flag is set by the consumer after allocating
  the tfm and before calling the function crypto_xxx_setkey().
