[CRYPTO] api: Kill crypto_km_types
When scatterwalk is built as a module digest.c was broken because it requires the crypto_km_types structure which is in scatterwalk. This patch removes the crypto_km_types structure by encoding the logic into crypto_kmap_type directly. In fact, this even saves a few bytes of code (not to mention the data structure itself) on i386 which is about the only place where it's needed.
