KVM: SVM: remove INIT intercept handler

commit 896707c upstream. 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 5ff3a35 ("KVM: x86: Move trivial instruction-based exit handlers to common code").
