Michal Wajdeczko d21d44dbdd drm/xe/vf: Don't touch GuC irq registers if using memory irqs
On platforms where VFs are using memory based interrupts, we
missed invalid access to no longer existing interrupt registers,
as we keep them marked with XE_REG_OPTION_VF. To fix that just
either setup memirq vectors in GuC or enable legacy interrupts.
