crypto: remove useless initializations of cra_list

Some algorithms initialize their .cra_list prior to registration. But this is unnecessary since crypto_register_alg() will overwrite .cra_list when adding the algorithm to the 'crypto_alg_list'. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignments. Exception: paes_s390.c uses cra_list to check whether the algorithm is registered or not, so I left that as-is for now. This patch shouldn't change any actual behavior.
