[XEN PATCH v1 09/15] x86/traps: guard vmx specific functions with CONFIG_VMX

[Sergiy Kibrik <Sergiy_Kibrik@xxxxxxxx>]

From: Xenia Ragiadakou <burzalodowa@xxxxxxxxx>

The functions vmx_vmcs_enter() and vmx_vmcs_exit() are VT-x specific.
Guard their calls with CONFIG_VMX.

No functional change intended.
