    Cygwin: don't copy path_conv in fhandler_base::reset
    
    There's a slim chance that duplicating fhandlers may end up duplicating
    path_conv_handle handles twice ending up with a handle leak, due to
    fhandler_base::reset calling path_conv::operator<< after the only
    caller, fhandler::copyto, already called path_conv::operator=.
    
    Just drop the call which basically duplicates what path_conv::operator=
    already did.
