[v5,5/8] Add migrate_set_ports into migrate_qmp to update migration port value

Commit Message

Het Gala March 11, 2024, 9:53 p.m. UTC

migrate_get_connect_qdict gets qdict with the dst QEMU parameters.

migrate_set_ports() from list of channels reads each QDict for port,
and fills the port with correct value in case it was 0 in the test.
