In case deferred_reset_pending is set in gk20a_fifo_handle_mmu_fault(), we skip
resetting the engines and skip setting the error notifier
Then we call gk20a_channel_abort()/gk20a_fifo_abort_tsg() which aborts the
channels, and resets the syncpoint values to release all the waiters
But since we don't set error notifier this could lead User to assume a
successful submission without any error
To fix this disable channel/TSG in case deferred_reset_pending is set and skip
calls to gk20a_channel_abort()/gk20a_fifo_abort_tsg()
Note that we finally abort the channel when channel is being closed
