drm/i915/gt: add sparse lock annotation to avoid warnings
Annotate intel_gt_mcr_lock() and intel_gt_mcr_unlock() to fix sparse
warnings:
drivers/gpu/drm/i915/gt/intel_gt_mcr.c:397:9: warning: context imbalance in 'intel_gt_mcr_lock' - wrong count at exit
drivers/gpu/drm/i915/gt/intel_gt_mcr.c:412:6: warning: context imbalance in 'intel_gt_mcr_unlock' - unexpected unlock
