mac80211: Checking a kmemdup() call in ieee80211_send_assoc()

Hello,

I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function “ieee80211_send_assoc” contains still an unchecked call
of the function “kmemdup”.

How do you think about to improve it?

Regards,
Markus
