schannel: Remove incorrect SNI disabled message
- Remove the SNI disabled when host verification disabled message
since that is incorrect.
- Show a message for legacy versions of Windows <= XP that connections
may fail since those versions of WinSSL lack SNI, algorithms, etc.
Bug: https://github.com/curl/curl/pull/1240
