[PATCH] debugfs: remove unused htree_dump "-l" argument

[Eric Sandeen <sandeen@redhat.com>]

The long_opt / -l argument was apparently never implemented,
so remove it and associated argument parsing.

This slightly changes the (undocumented) behavior because it
no longer defaults to cwd if no filespec is specified...
