Subject: [PATCH 11/12] crypto: sm3 - Remove the original "sm3_block_generic()"

From: Eric Biggers <[email-masked]>
Date: Fri, 20 Mar 2026 21:09:34 -0700

Since the architecture-optimized SM3 code was migrated into lib/crypto/,
sm3_block_generic() is no longer called.  Remove it.  Then, since this
frees up the name, rename sm3_transform() to sm3_block_generic()
(matching the naming convention used in other hash algorithms).
