I didn't really need to do much for the printk's in
ieee80211_sta_debugfs_add().  My printk's in sta_info_debugfs_add_work()
already told me that sta->local->debugfs.stations is NULL.  Again, this
is iwl3945 only after a suspend of a few minutes followed by a resume.
It happens about 1/3 of the time.

Thanks,
