tests/qtest: optimize migrate_set_ports

Browse Source 
Do not query connection parameters if all port numbers are known.  This is
more efficient, and also solves a problem for the cpr-transfer test.
At the point where cpr-transfer calls migrate_qmp and migrate_set_ports,
the monitor is not connected and queries are not allowed.  Port=0 is
never used for cpr-transfer.
