    Windows: increase timeout for extent request retries
    
    The AFS Redirector requests file data extents from the afsd_service.exe.  If
    it does not receive the requested extent within 10 seconds it issues another
    request for that extent.  Extent processing in the afsd_service is handled
    by background daemons that process tasks serially from a work queue.   When
    the load on the system is large enough that satisfying the work queue takes
    longer than 10 seconds, the redirector would retry the request.  This would
    increase the length of the work queue and increase lock contention.
    
    Increasing the timeout period for extent retries to two minutes
    significantly reduces the number of retry attempts while maintaining
    protection against a lost extent request.  Two minutes is selected because
    that is the rx hard dead call timeout.
