[XEN PATCH v2 13/15] x86/ioreq: guard VIO_realmode_completion with CONFIG_VMX

[Sergiy Kibrik <Sergiy_Kibrik@xxxxxxxx>]

From: Xenia Ragiadakou <burzalodowa@xxxxxxxxx>

VIO_realmode_completion is specific to vmx realmode, so guard the completion
handling code with CONFIG_VMX. Also, guard VIO_realmode_completion itself by
CONFIG_VMX, instead of generic CONFIG_X86.

No functional change intended.
