Commit Message

fix slh-dsa incorrect prediction of result code

The slh_dsa fuzzer predicts failure in EVP_message_sign_init in the
event we pass a context_string param of more than 255 bytes.  That makes
for an accurate prediction, but only if we actually create  the param.

augment the setting of exepct_rc_init to be determined not only by our
allocation of a > 255 byte message, but also on selector bit 1, which
determines if we create the parameter at all.
