[Xen-devel] [PATCH] vtd: only enable Interrupt Remapping if Queued Invalidation is also enabled.

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

If Queued Invalidation is not supported or not enabled, we should not enable
Interrupt Remapping even if HW supports it, because Interrupt Remapping needs
Queued Invalidation to invalidate Interrupt Remapping Cache.
