pidl: Fix array range checks in python output
Without this, we generated code like
if (ndr_table_dnsserver.num_calls < 0) {
PyErr_SetString(PyExc_TypeError, "Internal Error, ndr_interface_call missing for py_DnssrvOperation_ndr_pack");
return NULL;
}
call = &ndr_table_dnsserver.calls[0];
This does not really make sense, and Coverity found comparing the unsigned
num_calls against <0 a bit pointless.
Should fix 138 Coverity findings and make the code a bit more correct.
