gpu: nvgpu: preempt before adjusting fences
Current sequence in gk20a_disable_channel() is
- disable channel in gk20a_channel_abort()
- adjust pending fence in gk20a_channel_abort()
- preempt channel
But this leads to scenarios where syncpoint has
min > max value
Hence to fix this, make sequence in gk20a_disable_channel()
- disable channel in gk20a_channel_abort()
- preempt channel in gk20a_channel_abort()
- adjust pending fence in gk20a_channel_abort()
If gk20a_channel_abort() is called from other API where
preemption is not needed, then use channel_preempt
flag and do not preempt channel in those cases
