filp_open() can return ERR_PTR(). Keep that value out of the GC-backed userdata so meth_file_gc() never passes an error pointer to fput(). Store the file pointer in a temporary first and publish it to the userdata only after the open succeeds. Signed-off-by: Zongyao Chen <ZongYao.Chen@linux.alibaba.com>
