KVM: PPC: Update int_pending also on dequeue
When having a decrementor interrupt pending, the dequeuing happens manually through an mtdec instruction. This instruction simply calls dequeue on that interrupt, so the int_pending hint doesn't get updated. This patch enables updating the int_pending hint also on dequeue, thus correctly enabling guests to stay in guest contexts more often. Signed-off-by: Alexander Graf <agraf@suse.de>
