crypto: aead - Add type-safe init/exit functions
As it stands the only non-type safe functions left in the new
AEAD interface are the cra_init/cra_exit functions. It means
exposing the ugly __crypto_aead_cast to every AEAD implementor.
This patch adds type-safe init/exit functions to AEAD. Existing
algorithms are unaffected while new implementations can simply
fill in these two instead of cra_init/cra_exit.
