Wanpeng Li f85f6e7bc9 KVM: X86: Yield to IPI target if necessary
When sending a call-function IPI-many to vCPUs, yield if any of
the IPI target vCPUs was preempted, we just select the first
preempted target vCPU which we found since the state of target
vCPUs can change underneath and to avoid race conditions.
