bugfix: salt recheck will cause duplicated iv/salt error

[chuxi]

in version 1.14.3

        // Check repeated salt after first successful decryption #442
        if self.salt.is_some() {
            let salt = self.salt.take().unwrap();
            context.check_nonce_replay(&salt)?;
        }

current master version

        // Check repeated salt after first successful decryption #442
        if let Some(ref salt) = self.salt {
            context.check_nonce_replay(self.method, salt)?;
        }

if enable feature security-replay-attack-detect, it causes error detected repeated nonce (iv/salt)

we need to revert the code, or aead can not work in current version if we set reject policy.
