Windows: Disable hard dead timeout for RDR File Server connections

The UNIX cache manager does not implement hard dead timeouts
on file server connections.  The Windows cache manager had to
because of the SMB connection timeout requirements.  For the
AFS redirector there is no timeout requirement.  Therefore,
when the SMB stack is disabled the Windows cache manager can
disable the hard dead timeout.

The idle dead timeouts are in place to cancel connections when
file servers stop replying with real data.
