Subject: drm/i915/gvt: Use offsetofend() rather than offsetof + sizeof
Git-commit: 579e2f6d999991d2d2dd39c7185cba0a97137cee
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Compute the offset of the end of the crc32 field using offsetofend()
rather than open-coding.
