[CPT] Fail when VE refers to an invisible file Checkpointing used to ignore EINVAL returned by d_path(). It was workaround for tmpfs shmem files, which use detached mounts. But this means that real invisible paths are detected too late: checkpointing succeds and restore fails, which is not acceptable. When d_path() fails, check that it is shmem file. If it is not, fail immediately.
