Ken Chang 793f7deb94 gpu: nvgpu: error handling for gk20a_fence alloc ...

In current design, the new increments are added to the threshold for
fence allocation. So if it fails to get gk20a_fence, decrease the new
increments before bailing out from __gk20a_channel_syncpt_incr()
and propagating the error code.
