job->post_fence dma_fence is created for a syncpoint by nvgpu during submission. This fence is not freed after job completion as extra dma_fence reference (dma_fence_get) is taken in nvgpu_nvhost_fence_install. sync_file_create called from this function already takes one ref which will be dropped when the sync file is closed. dma_fence_get called here from nvgpu_nvhost_fence_install is not paired with corresponding put. Remove this dma_fence_get call to fix the dma_fence memleak.
