KVM: SVM: remove INIT intercept handler

Browse source

commit 896707c212 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 5ff3a351f6 ("KVM: x86: Move trivial
instruction-based exit handlers to common code").
