crypto: algapi - pass instance to crypto_grab_spawn()
Currently, crypto_spawn::inst is first used temporarily to pass the instance to crypto_grab_spawn(). Then crypto_init_spawn() overwrites it with crypto_spawn::next, which shares the same union. Finally, crypto_spawn::inst is set again when the instance is registered. Make this less convoluted by just passing the instance as an argument to crypto_grab_spawn() instead.
