Divya Singhatwaria c060e754fc gpu: nvgpu: ELPG dump stats at shutdown
ELPG_DISALLOW command fails during gk20a shutdown.
It was due to nvgpu_can_busy() which was returning
0 before without acknowledging the ELPG_DISALLOW
command.

Since the system is shutting down so fix this issue
by setting the ACK for disallow command without
waiting for actual ACK from PMU.
In doing so the state machine is also maintained
properly and the driver does not dump fail stats.
