schannel: fix compiler warning

Browse Source 
When building with Unicode on MSVC, the compiler warns about freeing a
pointer to const in Curl_unicodefree. Fix this by declaring it as
non-const and casting the argument to Curl_convert_UTF8_to_tchar to
non-const too, like we do in all other places.

Closes https://github.com/curl/curl/pull/3435
