Upon writing to "remove" file, debugfs_remove_recursive() blocks while holding rtnl_lock. This is because debugfs' file_ops callbacks are executed in debugfs_use_file_*() context which prevents file removal. Fix this by only flagging the device for removal and then do the cleanup in file_ops.release callback which is executed out of that context.
