Linux 6.18 compat: Drop hmac_sha256 symbol (#277)
* Linux 6.18 compat: Drop `hmac_sha256` symbol

It looks like it is a backwards compatibility code piece, I could find any
occurence of it outside of the core/crypto/sha256.{c,h} and it looks like
driver uses `hmac_sha256_vector` directly anyway that this function was a
(legacy?) wrapper for.
