Modified: trunk/batman-adv-kernelland/bat_debugfs.c Log: batman-adv: Ignore debugfs on kernels without debugfs support

All code for debugfs is ignored when the creation of the batman-adv root directory in debugfs fails. It must also be ignored when the debugfs_create_dir tells us that debugfs is not implemented to prevent a crash during the unload of the module.
