When `USE_OPENSSL` was defined but OpenSSL had no DES support and a different crypto library was used for that, `Curl_des_set_odd_parity` was called but not defined. This could for example happen on Windows and macOS when using OpenSSL v3 with deprecated features disabled. Use the same condition for the function definition as used at the caller side, but leaving out the OpenSSL part to avoid including OpenSSL headers. Closes https://github.com/curl/curl/pull/8459

* Curl_des_set_odd_parity()
|
|
*
|
|
* This is used to apply odd parity to the given byte array. It is typically
|
|
* used by when a cryptography engines doesn't have it's own version.
|
|
*
|
|
* The function is a port of the Java based oddParity() function over at:

* https://davenport.sourceforge.io/ntlm.html
|

|
|
* Parameters:
|
|
*
|
|
* bytes [in/out] - The data whose parity bits are to be adjusted for
|
|
* odd parity.
|
|
* len [out] - The length of the data.
