Currently, the alignment of each field in struct aesni_xts_ctx occurs right before every access. However, it's possible to perform this alignment ahead of time. Introduce a helper function that converts struct crypto_skcipher *tfm to struct aesni_xts_ctx *ctx and returns an aligned address. Utilize this helper function at the beginning of each XTS function and then eliminate redundant alignment code.
