KVM: x86: Do not change ICR on write to APIC_SELF_IPI
[ Upstream commit d22a81b304a27fca6124174a8e842e826c193466 ]
Emulating writes to SELF_IPI with a write to ICR has an unwanted side effect:
the value of ICR in vAPIC page gets changed. The lists SELF_IPI as write-only,
with no associated MMIO offset, so any write should have no visible side
effect in the vAPIC page.
