Kernel never sends real INIT even to CPUs, other than on boot.
Thus INIT interception is an error which should be caught
by a check for an unknown VMexit reason.
On top of that, the current INIT VM exit handler skips
the current instruction which is wrong.
That was added in commit 5ff3a351f687 ("KVM: x86: Move trivial
instruction-based exit handlers to common code").
