Coverity reports potential NULL pointer dereference in get_supported_hv_cpuid_legacy() when 'cs->kvm_state' is NULL. While 'cs->kvm_state' can indeed be NULL in hv_cpuid_get_host(), kvm_hyperv_expand_features() makes sure that it only happens when KVM_CAP_SYS_HYPERV_CPUID is supported and KVM_CAP_SYS_HYPERV_CPUID implies KVM_CAP_HYPERV_CPUID so get_supported_hv_cpuid_legacy() is never really called. Add asserts to strengthen the protection against broken KVM behavior.
