Function debugfs_remove() recursively removes a directory, include all
files created by debugfs_create_file(). Therefore, there is no need to
explicitly record each file with member ->bnad_dentry_files[] and
explicitly delete them at the end. Delete field bnad_dentry_files[] and
its related processing codes for optimization.
