[PATCH 7/8] mac80211: don't check if key is NULL in ieee80211_key_link()

[Luca Coelho <luca@xxxxxxxxx>]

From: Luca Coelho <luciano.coelho@xxxxxxxxx>

We already assume that key is not NULL and dereference it in a few
other places before we check whether it is NULL, so the check is
unnecessary.  Remove it.

Fixes: 96fc6efb9ad9 ("mac80211: IEEE 802.11 Extended Key ID support")
