gpu: nvgpu: use full system barrier in BAR1 test
BAR1 test could occasionally fail when doing CPU write through userd
then reading back through BAR1. This is because nvgpu_smp_mb() only
guarantees ordering between cores.
Replaced with nvgpu_mb() to ensure the write will be visible to all
bus masters in the system.
