crypto: user - Fix lookup of algorithms with IV generator
We lookup algorithms with crypto_alg_mod_lookup() when instantiating via crypto_add_alg(). However, algorithms that are wrapped by an IV genearator (e.g. aead or genicv type algorithms) need special care. The userspace process hangs until it gets a timeout when we use crypto_alg_mod_lookup() to lookup these algorithms. So export the lookup functions for these algorithms and use them in crypto_add_alg().
