cfg80211/mac80211: use debugfs_remove_recursive
We can save a lot of code and pointers in the structs by using debugfs_remove_recursive(). First, change cfg80211 to use debugfs_remove_recursive() so that drivers do not need to clean up any files they added to the per-wiphy debugfs (if and only if they are ok to be accessed until after wiphy_unregister!). Then also make mac80211 use debugfs_remove_recursive() where necessary -- it need not remove per-wiphy files as cfg80211 now removes those, but netdev etc. files still need to be handled but can now be removed without needing struct dentry pointers to all of them.
