Staging: batman-adv: Ignore debugfs on kernels without debugfs support

Browse source 
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
possible crashes in the future.
