Keep any error reported by the gup_worker until we are notified that the arena has changed (via the mmu-notifier). This has the importance of making two consecutive calls to i915_gem_object_get_pages() reporting the same error, and curtailing a loop of detecting a fault and requeueing a gup_worker. Signed-off-by:
