Subject: [PATCH 02/20] staging/lustre: make ldebugfs_remove recursive

From: Oleg Drokin <green@...uxhacker.ru>

ldebugfs_remove is usually called on directories with files passed in
as attributes, so simple debugfs_remove failes on them as not empty
Switch to debugfs_remove_recursive.

This fixes a number of problems where a new filesystem is mounted after
being unmounted first.
