drm/i915/guc: avoid FIELD_PREP warning

Browse Source 
[ Upstream commit d4f36db62396b73bed383c0b6e48d36278cafa78 ]

With gcc-7 and earlier, there are lots of warnings like

In file included from <command-line>:0:0:
In function '__guc_context_policy_add_priority.isra.66',
    inlined from '__guc_context_set_prio.isra.67' at drivers/gpu/drm/i915/gt/uc/intel_guc_submission.c:3292:3,

  _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)

drivers/gpu/drm/i915/gt/uc/intel_guc_submission.c:2422:3: note: in expansion of macro 'FIELD_PREP'
   FIELD_PREP(GUC_KLV_0_KEY, GUC_CONTEXT_POLICIES_KLV_ID_##id) | \
   ^~~~~~~~~~

Make sure that GUC_KLV_0_KEY is an unsigned value to avoid the warning.
