[Intel-gfx] [PATCH] drm/i915: unmap the correct pointer in i915_error_object_create()

[Dan Carpenter]

We should be unmapping "page" instead of "s".  This code originally used
kmap_atomic() before it was changed to kmap().  The two mapping
functions are different which leads to this common mistake.
