KVM: allow host header to be included even for !CONFIG_KVM 

The new context tracking subsystem unconditionally includes kvm_host.h
headers for the guest enter/exit macros.  This causes a compile
failure when KVM is not enabled.

Fix by adding an IS_ENABLED(CONFIG_KVM) check to kvm_host so it can
be included/compiled even when KVM is not enabled.
