[tor-commits] [tor/master] Prevent duplicate initialization of NSS DH module

    Prevent duplicate initialization of NSS DH module
    
    Allowing this didn't do any actual harm, since there aren't any
    shared structures or leakable objects here.  Still, it's bad style
    and might cause trouble in the future.
    
    Closes ticket 27856.
