Paul E. McKenney 190db3b1da drm/xe: Fix build bug for GCC 11 
Building drivers/gpu/drm/xe/xe_gt_pagefault.c with GCC 11 results
in the following build errors:

Fix these by removing -Wstringop-overflow from drm/xe builds.

Closes: https://lore.kernel.org/all/45ad1d0f-a10f-483e-848a-76a30252edbe@paulmck-laptop/
Fixes: 7a8bc11782 ("drm/xe: Enable W=1 warnings by default")
Suggested-by: Stephen Rothwell <sfr@rothwell.id.au>
Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
[ This particular warning is broken on GCC11. In future changes it will
  be moved to the normal C flags in the top level Makefile (out of
  Makefile.extrawarn), but accounting for the compiler support. Just
  remove it out of xe's forced extra warnings for now ]
