x86: replace CONFIG_HAVE_KVM with IS_ENABLED(CONFIG_KVM)
It is more accurate to check if KVM is enabled, instead of having the
architecture say so. Architectures always "have" KVM, so for example
checking CONFIG_HAVE_KVM in x86 code is pointless, but if KVM is disabled
in a specific build, there is no need for support code.
Alternatively, many of the #ifdefs could simply be deleted. However,
this would add completely dead code. For example, when KVM is disabled,
there should not be any posted interrupts, i.e. NOT wiring up the "dummy"
handlers and treating IRQs on those vectors as spurious is the right
thing to do.
