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

[Markus Elfring]

Hello,

I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function âieee80211_send_assocâ contains still an unchecked call
of the function âkmemdupâ.

https://elixir.bootlin.com/linux/v5.4-rc2/source/net/mac80211/mlme.c#L980

How do you think about to improve it?

Regards,
Markus
