mac80211: fix debugfs lockup
When debugfs_create_dir fails, sta_info_debugfs_add_work will not terminate because it will find the same station again and again. This is possible whenever debugfs fails for whatever reason; one reason is a race condition in mac80211, unfortunately we cannot do much about it, so just document it, it just means some station may be missing from debugfs.
