crng_fast_load() and crng_slow_load() have different semantics: - crng_fast_load() xors and accounts with crng_init_cnt. - crng_slow_load() hashes and doesn't account. However add_hwgenerator_randomness() can afford to hash (it's called from a kthread), and it should account. Additionally, ones that can afford to hash don't need to take a trylock but can take a normal lock. So, we combine these into one function, crng_pre_init_inject(), which allows us to control these in a uniform way. This will make it simpler later to simplify this all down when the time comes for that.
