KVM: Avoid double interrupt injection with vapic
After an interrupt injection, the PPR changes, and we have to reflect that
into the vapic. This causes a KVM_REQ_EVENT to be set, which causes the
whole interrupt injection routine to be run again (harmlessly).
Optimize by only setting KVM_REQ_EVENT if the ppr was lowered; otherwise
there is no chance that a new injection is needed.
