    libfetch: Fix handling of connection failures
    
    After commit 848f360c8f9a, if one tries to connect to a closed port,
    fetch reports "Operation now in progress", which is rather confusing.
    Return a more useful error message, restoring the old behaviour.
    
    Fixes:          848f360c8f9a ("libfetch: Apply timeout to connection attempts")
