Deepak Nibade 4942cc4222 gpu: nvgpu: wait for idle in shutdown ...

In gk20a_pm_shutdown(), we currently do not wait
for IOCTLs or threads in progress and directly
proceed with shutdown sequence

This can cause random hangs during system shutdown

Fix this by calling gk20a_wait_for_idle() after
we disable runtime PM in gk20a_pm_shutdown()
