drm/xe: Remove PVC from xe_wa kunit tests

Since the PCI IDs for PVC weren't added to the xe driver, the xe_wa
tests should not try to create a fake PVC device since they can't find
the right PCI ID. Fix bugs when running kunit:

	# xe_wa_gt: ASSERTION FAILED at drivers/gpu/drm/xe/tests/xe_wa_test.c:111
	Expected ret == 0, but
	    ret == -19 (0xffffffffffffffed)
	[FAILED] PVC (B0)
	# xe_wa_gt: ASSERTION FAILED at drivers/gpu/drm/xe/tests/xe_wa_test.c:111
	Expected ret == 0, but
	    ret == -19 (0xffffffffffffffed)
	[FAILED] PVC (B1)
	# xe_wa_gt: ASSERTION FAILED at drivers/gpu/drm/xe/tests/xe_wa_test.c:111
	Expected ret == 0, but
	    ret == -19 (0xffffffffffffffed)
	[FAILED] PVC (C0)
