[Qemu-devel] [RFC PATCH v1 6/9] cpus: check cpu->running in cpu_get_icount_raw() |

The lifetime of current_cpu is now the lifetime of the vCPU thread.
However get_icount_raw() can apply a fudge factor if called while code
is running to take into account the current executed instruction
count.
To ensure this is always the case we also check cpu->running.
