Terje Bergstrom 4bd9682c92 gpu: nvgpu: Reset priv ring properly on error
We did not follow the proper sequence to reset priv ring on error.
Instead we just re-enabled priv ring, which does not reset anything.

Rename the gk20a_reset_priv_ring() to gk20a_enable_priv_ring() to
indicate its proper use. Add another gk20a_reset_priv_ring() which
actually resets priv ring properly.
