[XEN PATCH v3 08/16] x86/p2m: guard EPT functions with using_vmx macro

[Sergiy Kibrik <Sergiy_Kibrik@xxxxxxxx>]

From: Xenia Ragiadakou <burzalodowa@xxxxxxxxx>

Replace cpu_has_vmx check with using_vmx, so that presence of functions
ept_p2m_init() and ept_p2m_uninit() in the build gets checked.
Since currently Intel EPT implementation depends on CONFIG_VMX config option,
when VMX is off these functions are unavailable.
