You marked this for wireless-next so should I take this directly?

Does this fix something or is just cleanup? It would be good to mention
that in the commit log.

Not a fix, just cleanup. I will take this for the next cycle.

it is not a fix, "wireless-next" is just the default subjectprefix for my
git tree, sorry for the confusion. I think it can go through Felix's tree.

`msta` may be a null pointer. This patch may cause data to be written to a
null pointer in `return mt76x02_mac_wcid_set_key(dev, msta->wcid.idx, key);`.
