OpenSSL 3 regressions in HMAC algorithms

[keeshux]

Might well be two symptoms of the same illness:

• OpenVPNErrorCodeCryptoEncryption (103) - Fixed in HMAC breaking due to dangling OSSL_PARAM #405
• OpenVPNErrorCodeTLSCAPeerVerification (203) - Fixed in Set SSL security level explicitly #406

Got one OpenSSL failure at this line:

tunnelkit/Sources/CTunnelKitOpenVPNProtocol/CryptoCBC.m

Line 180 in 138f1ca

TUNNEL_CRYPTO_TRACK_STATUS(code) EVP_MAC_init(ctx, self.hmacKeyEnc.bytes, self.hmacKeyEnc.count, self.macParams);

right after "TLS.connect: Handshake is complete".

As weird as it sounds, the above issue is resolved by not reusing the OSSL_PARAM structure for HMAC. Unless I corrupt it at some point, which is very hard to track down.

#405 doesn't fix error 203.
