Subject: [PATCH][next] drm/i915/gt: remove redundant pointer sseu

Pointer sseu is being assigned a value that is never read. The pointer
is redundant and can be removed. Cleans up clang scan warning:

drivers/gpu/drm/i915/gt/uc/intel_guc_capture.c:300:2: warning: Value stored
to 'sseu' is never read [deadcode.DeadStores]
