[PATCH] cfg80211: use debugfs_rename

[Johannes Berg <johannes@sipsolutions.net>]

Use the new debugfs_rename function in mac80211's debugfs where
necessary and fix a bug with renaming.

Signed-off-by: Johannes Berg <johannes@sipsolutions.net>

debugfs_rename hasn't actually been merged yet, but I hope it will be
merged soon. URL is

This patch should also apply against net-2.6 (with some fuzz though due
to the nl80211 bit)
