Terje Bergstrom cd13ee4aaf gpu: nvgpu: Set ch error before channel disable ...

In error case we first disabled the channel, and reset sync point to
max. After this we set channel error state. This causes a race if
channel is closed between setting sync point and setting channel
state.

Rearrange the code so that error state is set first, and only then
channel is disabled.
