[PATCH] kvm: always inline vmx_vcpu_run()

[Qian Cai]

__noclone was removed from vmx_vcpu_run() in 453eafbe65f which causes a
compilation warning using GCC 8,

arch/x86/kvm/vmx/vmx.o: warning: objtool: vmx_vcpu_run.part.17()+0x3171:
call without frame pointer save/setup

GCC decides to splits the function into small parts for optimization
which confuses STACK_FRAME_NON_STANDARD(vmx_vcpu_run). Hence, just
inline the whole function to avoid this.

Fixes: 453eafbe65f (KVM: VMX: Move VM-Enter + VM-Exit handling to
non-inline sub-routines)
