Unconditionally set the allocated flag when initializing a hash state
structure. When running multiple concurrent unit tests, I observed multiple failures in the hmac tests, which I ultimately tracked down to different clients sharing the same hal_hmac_state struct. hal_hash_initialize is called twice in hal_hmac_initialize (once to get the state structure, then again if the supplied key is too long), and is called in hal_hmac_finalize, to hash the digest with the supplied key. In these subsequent cases, the caller supplies the state structure, which hal_hash_initialize zeroes, but it doesn't set the allocated flag. This marks an in-use struct as available, so it gets reassigned and reinitialized, and Bad Things Happen for both clients that are trying to use it.
