There's no need to check level (CPUID[0].EAX) before calling
kvm_arch_get_supported_cpuid(s, 0x7, 0, R_EBX), because:
* The kernel won't return any entry for CPUID 7 if CPUID[0].EAX is < 7
(See kvm_dev_ioctl_get_supported_cpuid() on the kernel code);
* kvm_arch_get_supported_cpuid() will return 0 if no entry is returned
by the kernel for the requested leaf.
This will simplify the kvm_cpu_fill_host() code a little.
