Mike Gilbert 8481e3e71e basic: detect_vm_cpuid: fix hypervisor detection
The __get_cpuid() function only calls __cpuid() if __get_cpuid_max()
returns a value that is less than or equal to the leaf value.

In QEMU/KVM, I found that the special hypervisor leaf value (0x40000000U)
is always larger than the value retured by __get_cpuid_max().

Avoid this problem by calling the __cpuid() macro directly once we have
checked the hypervisor bit from leaf 1.
