This parameter need compare with the return of qemu_clock_get_ms(),
it is uinit64_t. So we need fix this issue here.

The virtual clock only runs during the emulation. It stops
when the virtual machine is stopped.
The host clock should be used for device models that emulate accurate
real time sources. It will continue to run when the virtual machine
is suspended. COLO need to know the host time here.

Re-checked glib code, it just checked the queue rather than inside content.
Maybe check empty before that will benefit performance.
