qemuMigrationSrcPerformTunnel: Remove 'migrate_disks' argument

Any QEMU we support requires use of NBD for disk migration which is not
supported with tunnelled migration. This is validated in
'qemuMigrationSrcBeginPhase'. Passing the list of disks to migrate is
thus pointless. Remove the argument.
