KVM: Use cond_resched() directly and remove useless kvm_resched()
Since the commit 15ad7146 ("KVM: Use the scheduler preemption notifiers to make kvm preemptible"), the remaining stuff in this function is a simple cond_resched() call with an extra need_resched() check which was there to avoid dropping VCPUs unnecessarily. Now it is meaningless. Signed-off-by: Takuya Yoshikawa <yoshikawa_takuya_b1@lab.ntt.co.jp> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
