[0/2] KVM: x86: Fix more KVM_X86 Kconfig bugs

Fix two more bugs in the KVM_X86 Kconfig.  The fix from Arnd resolves a
build failure, but practically speaking is a non-issue because the failure
only affects 32-bit !SMP builds that effectively disable the local APIC.

The second fix is far more urgent.  It resolves a bug where KVM's Kconfig
doesn't correctly define KVM_X86, and will build kvm.ko as a module when
KVM=y if neither KVM_INTEL nor KVM_AMD is 'y', e.g. if KVM=y, KVM_INTEL,=m,
and KVM_AMD=m.  I don't know if any distros use that combo, but it broke
our production kernel, so it's certainly possible that it broke other
setups too.

Arnd's fix was already posted, but I bundled it here to avoid a trivial
conflict and to ensure it doesn't get left behind.

  KVM: x86: Break CONFIG_KVM_X86's direct dependency on KVM_INTEL ||
    KVM_AMD
