David Woodhouse 5a169bf04c x86/kvm: Reserve KVM_FEATURE_MSI_EXT_DEST_ID
No functional change; just reserve the feature bit for now so that VMMs
can start to implement it.

This will allow the host to indicate that MSI emulation supports 15-bit
destination IDs, allowing up to 32768 CPUs without interrupt remapping.
