From: xinhui pan <xinhui.pan@xxxxxxx> [ Upstream commit 4eb6bb649fe041472ddd00f94870c0b86ef49d34 ] amdgpu_amdkfd_gpuvm_free_memory_of_gpu drop dmabuf reference increased in amdgpu_gem_prime_export. amdgpu_bo_destroy drop dmabuf reference increased in amdgpu_gem_prime_import. So remove this extra dma_buf_put to avoid double free.
