KVM: x86: Check that the high 32bits are clear in kvm_arch_vcpu_ioctl_run()
The "kvm_run->kvm_valid_regs" and "kvm_run->kvm_dirty_regs" variables are
u64 type. We are only using the lowest 3 bits but we want to ensure that
the users are not passing invalid bits so that we can use the remaining
bits in the future.
However "sync_valid_fields" and kvm_sync_valid_fields() are u32 type so
the check only ensures that the lower 32 bits are clear. Fix this by
changing the types to u64.
