open("/proc/pid/$anon-fd") should fail, we can't create the new
file with correct f_op/etc correctly. Currently this creates the
bogus file with the empty anon_inode_fops, this is harmless but
still wrong and misleading.Add anon_inode_fops->anon_open() which simply returns ENXIO like sock_no_open() does in this case.
