ANDROID: Fix x86_64 allmodconfig build

CONFIG_KVM_INTEL depends on asm volatile goto which is about to be
supported in clang, but we haven't landed the upgraded compiler yet.
Suppress use of this kernel feature for now.

In file included from arch/x86/kvm/vmx/vmx.h:11:
arch/x86/kvm/vmx/ops.h:157:2: error: 'asm goto' constructs are not
supported yet
vmx_asm2(vmwrite, "r"(field), "rm"(value), field, value);
^
