Jan H. Schönherr 3a8b0677fc KVM: VMX: Do not BUG() on out-of-bounds guest IRQ 
The value of the guest_irq argument to vmx_update_pi_irte() is
ultimately coming from a KVM_IRQFD API call. Do not BUG() in
vmx_update_pi_irte() if the value is out-of bounds. (Especially,
since KVM as a whole seems to hang after that.)

Instead, print a message only once if we find that we don't have a
route for a certain IRQ (which can be out-of-bounds or within the
array).

This fixes CVE-2017-1000252.

Fixes: efc644048e ("KVM: x86: Update IRTE for posted-interrupts")
