gpu: nvgpu: fix boardobjgrp getstatus error on gv10x

Req : Some boardobjgrp don't need getstatus support, so
boardobjgrp pmu cmd not constructed for those boardobjgrp.
Don't request memory alloc if boardobjgrp pmu cmd
not constructed & should exit cleanly without allocating memory.

Fix: Don't request memory alloc if boardobjgrp pmu cmd
not constructed by checking "sturct boardobjgrp_pmu_cmd"
member "fbsize" value.
