Don't call into ext2fs_get_pathname() to do a name lookup for a disconnected directory, since the directory block traversal in pass1 has already scanned all of the leaf blocks and never finds the entry, always printing "???". If the name entry had been found earlier, the directory would not be disconnected in pass3. Instead, lookup ".." and print the parent name in the prompt, and then do not search for the current directory name at all. This avoids a useless full directory scan for each disconnected entry, which can potentially be slow if the parent directory is large. Separate the recursively looped directory case to a new error code, since it is a different problem that should use its own descriptive text, and a proper pathname can be shown in this case.
