[PATCH]crypto: Fix aesni algorithm implementation without test

[Youquan,Song]

when load aesni-intel driver,kernel will report no test for some algorithm
with AES-NI. The strange information as following:

alg: No test for __aes-aesni (__driver-aes-aesni)
alg: No test for __ecb-aes-aesni (__driver-ecb-aes-aesni)
alg: No test for __cbc-aes-aesni (__driver-cbc-aes-aesni)
alg: No test for __ecb-aes-aesni (cryptd(__driver-ecb-aes-aesni)

crypto_alg's cra_name is use to descript algorithm itself, do not care the 
concrete implement. So this patch unify them and also can fix the algorithm
implementation without test.

No this is bogus.  The algorithm name is specifically set to these
values because they're not meant to be used directly by anyone other
than aesni.
