crypto: talitos - stop using crypto_ahash::init

Browse Source 
The function pointer crypto_ahash::init is an internal implementation
detail of the ahash API that exists to help it support both ahash and
shash algorithms.  With an upcoming refactoring of how the ahash API
supports shash algorithms, this field will be removed.

Some drivers are invoking crypto_ahash::init to call into their own
code, which is unnecessary and inefficient.  The talitos driver is one
of those drivers.  Make it just call its own code directly.
