crypto: aesni-intel - move more common code to ablk_init_common
ablk_*_init functions share more common code than what is currently in ablk_init_common. Move all of the common code to ablk_init_common. Cc: Huang Ying <ying.huang@intel.com> Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
