We use muldiv64() to compute the time to wait:
timeout = muldiv64(get_ticks_per_sec(), timeout, 33000000);
but get_ticks_per_sec() is 10^9 (30 bit value) and timeout
is a 35 bit value.
Whereas muldiv64 is:
uint64_t muldiv64(uint64_t a, uint32_t b, uint32_t c)
So we loose 3 bits of timeout.
Swapping get_ticks_per_sec() and timeout fixes it.
We can also replace it by a multiplication by 30 ns,
but this changes PCI clock frequency from 33MHz to 33.333333MHz
and we need to do this on all the QEMU PCI devices (later...)
