commit 3e2d06bd3d574eb47ec27edcc6832ed9678e7863

    Make hidden services always check for failed intro point connections
    
    Previously, they would stop checking when they exceeded their intro point
    creation limit.
    
    Fixes bug 21596; bugfix on commit d67bf8b2f23 in Tor 0.2.7.2-alpha.
    Reported by alecmuffett.
