crypto: shash - Fix has_key setting

commit 00420a65fa2beb3206090ead86942484df2275f3 upstream.

The has_key logic is wrong for shash algorithms as they always
have a setkey function.  So we should instead be testing against
shash_no_setkey.

Fixes: a5596d633278 ("crypto: hash - Add crypto_ahash_has_setkey")
