crypto: api - Move alg ref count init to crypto_check_alg
We currently initialise the crypto_alg ref count in the function __crypto_register_alg. As one of the callers of that function crypto_register_instance needs to obtain a ref count before it calls __crypto_register_alg, we need to move the initialisation out of there. Since both callers of __crypto_register_alg call crypto_check_alg, this is the logical place to perform the initialisation.
