[PATCH] drm/virtio: Fix NULL vs IS_ERR checking in virtio_gpu_object_shmem_init

Since drm_prime_pages_to_sg() function return error pointers. The drm_gem_shmem_get_sg_table() function returns error pointers too. Using IS_ERR() to check the return value to fix this. Fixes: f651c8b05542("drm/virtio: factor out the sg_table from virtio_gpu_object") Signed-off-by: Miaoqian Lin
