gpu: nvgpu: skip missing gpc_tpc_count in gr dumps
The gv11b and gm20b gr status reg dumps can get printed so early that
this array is null, so don't access it in that case.
Commit 946f1e635963d20f1e9f8020024c781448bfeb2d ("gpu: nvgpu: don't read
missing gpc_tpc_count in dump") fixed this for gp10b only.
