[PATCH 18/20] headers: add crypto/utils.h redirect for kernels < 6.6

[Yi Cong <cong.yi@linux.dev>]

From: Yi Cong <yicong@kylinos.cn>

In v6.6 crypto_xor(), crypto_xor_cpy(), and crypto_memneq() were
moved from crypto/algapi.h to a new crypto/utils.h header. For older
kernels, redirect to the original location.
