Milan Broz 7b6feb20b4 crypto_backend: remove superfluous memset fot hash and hmac contexts ...

The crypto backend crypt_hash ans crypt_hmac structs usually
contain only pointers to internal crypto lib structures, no need
to wipe them explicitly as there are no sensitive data.
It is a crypto lib responsibility to remove sensitive data
in destructor.

Only nettle backend directly contains hash context, keep it there.

This should also fix mysterious crashes in fuzzer with misaligned memset.
