Tom Hughes b07016348b mac80211: clear subdir_stations when removing debugfs ...

commit 4479004e64 upstream.

If we don't do this, and we then fail to recreate the debugfs
directory during a mode change, then we will fail later trying
to add stations to this now bogus directory:

BUG: unable to handle kernel NULL pointer dereference at 0000006c
