gpu: nvgpu: drop num_pts argument in nvgpu_nvhost_sync_create_fence

For nvhost_sync_create_fence, num_pts corresponds to the number of
syncpoints in the array given to it, and the wrapper
nvgpu_nvhost_sync_create_fence only supports one syncpoint at a time.
Use 1 explicitly and make it impossible for the caller of this wrapper
to use something else by mistake.
