drm/xe: Fix build without debugfs

Browse Source 
When CONFIG_DEBUG_FS is off, drivers/gpu/drm/xe/xe_gt_debugfs.o
is not built and build fails on some setups with:

	ld: drivers/gpu/drm/xe/xe_gt.o: in function `xe_fault_inject_gt_reset':
	drivers/gpu/drm/xe/xe_gt.h:27:(.text+0x1659): undefined reference to `gt_reset_failure'
	ld: drivers/gpu/drm/xe/xe_gt.h:27:(.text+0x1c16): undefined reference to `gt_reset_failure'
	collect2: error: ld returned 1 exit status

Do not use the gt_reset_failure attribute if debugfs is not enabled.
