Intel VT-D: Don't turn x2APIC if there is a missing DRHD entry for the IOAPIC.
Follow the Linux kernel lead in which the x2APIC is only turned on
only if there is an DRHD entry for all IOAPICs in the system. If we
don't do this we might enable x2APIC and see various devices not
covered by the IOAPIC mentioned in DRHD, not receive any interrupts.
