headers: fix problem when unloading mac80211 on Ubuntu 14.04
Upstream commit: 7f3a23738b01aa405c99bcf8f2be48ddf1956da4
When unloading mac80211 on the default kernel which is currently
shipped in Ubuntu 14.04 this commit causes a kernel error message. Now
we check if the list was deleted before and only do so if it was not
done before. Ubuntu probably backported this patch in their kernel.
