drm/xe/memirq: Update interrupt handler logic
To workaround some corner case hardware limitations, new programming
note for the memory based interrupt handler suggests to assume that
some status bytes, like GT_MI_USER_INTERRUPT and GUC_INTR_GUC2HOST,
are always set. Update our interrupt handler to follow the new rules.
