Subject: wl12xx: don't remove key if hlid was already deleted
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b42f068baab96a899bb5488ad9f0e72b14743ec5;p=mv-sheeva.git

wl12xx: don't remove key if hlid was already deleted

If hlid was already removed, there is no need to remove
its key (it might cause a fw crash, as the key is invalid).
