apic->pending_events processing has a race that may cause INIT and
SIPI
processing to be reordered:
vpu0: vcpu1:
set INIT
test_and_clear_bit(KVM_APIC_INIT)
process INIT
set INIT
set SIPI
test_and_clear_bit(KVM_APIC_SIPI)
process SIPI
At the end INIT is left pending in pending_events. The following patch
fixes this by latching pending event before processing them.
