kvm: some fixes to kvm_resamplefds_allowed

Commit f41389ae introduced kvm_resamplefds_enabled() and
associated kvm_resamplefds_allowed boolean. This patch adds
non-KVM version for kvm_resamplefds_enabled and also declares
kvm_resamplefds_allowed in kvm-stub as it is done for fellow
kvm_irqfds_allowed.
