X-Git-Tag: v2.6.39-rc1~468^2~417^2~61^2~35

wl12xx: remove redundant debugfs_remove_recursive() call

Upon rmmod, the <debugfs>/ieee80211/phyX dir is being removed.
later, we try to remove <debugfs>/ieee80211/phyX/wl12xx, which
might result in NULL dereference.

Remove the excessive debugfs_remove_recursive() call.
(consequently, there is no more need to save wl->rootdir)
