avformat/http: Ensure same protocol in ff_http_do_new_request2

Browse Source 
This can happen for HLS with AES-128 at the middle of m3u8, so old
protocol is https while new protocol is crypt+https.

And change the log level from ERROR to INFO when protocol/host/port
don't match. User should prepared for this function to fail and
retry with new connection.
