kernel: drm/i915: Fix potential overflow of shmem scatterlist length

A flaw was found in the Linux kernel's graphics memory management drm/i915 component. This vulnerability occurs when a large shared memory object's internal list of memory segments, called a scatterlist, is populated. If the total size of these segments exceeds 4 Gigabytes GB, a numerical overflo...
