configfs_detach_prep(): pass configfs_dirent instead of dentry
The only thing it uses the argument for is its ->d_fsdata and all callers have that already available. Note that in the recursive call we are dealing with a (sub)directory configfs_dirent, and for those ->s_dentry->d_fsdata points back to configfs_dirent itself.
