crypto: algapi - reject NULL crypto_spawn::inst
It took me a while to notice the bug where the adiantum template left crypto_spawn::inst == NULL, because this only caused problems in certain cases where algorithms are dynamically loaded/unloaded. More improvements are needed, but for now make crypto_init_spawn() reject this case and WARN(), so this type of bug will be noticed immediately in the future. Note: I checked all callers and the adiantum template was the only place that had this wrong. So this WARN shouldn't trigger anymore.
