Per
https://www.qemu.org/docs/master/devel/clocks.html#clock-multiplier-and-divider-settings:
Note that clock_set_mul_div() does not automatically call
clock_propagate(). If you make a runtime change to the
multiplier or divider you must call clock_propagate() yourself.
Fix what we forgot to do that in recent commit ec7d83acbd
