Small function declaration cleanup in slow-hash.c

- These functions are declared twice in slow-hash.c. Remove one of the copies.
- The declarations have the wrong return type, should be void, not int.

Function definitions here: https://github.com/monero-project/monero/blob/1e74586ee99e4bd89626d2eb4d23883cd91f0f81/src/crypto/aesb.c#L151-L180
Test plan: make release-test
