Add NULL check for gen->gi_code in gen_send_ex()
_PyGen_Finalize() checks that gen->gi_code is not NULL before it accesses the flags of the code object. This means that the flag could be NULL. It passes down the generatore to gen_close() and gen_send_ex(). gen_send_ex() did not check for gen->gi_code != NULL. CID 1297900
