Intel AES-NI AES acceleration instructions touch XMM state, to use
that in soft_irq context, general x86 AES implementation is used as
fallback. The first parameter is changed from struct crypto_tfm * to
struct crypto_aes_ctx * to make it easier to deal with 16 bytes
alignment requirement of AES-NI implementation.
