ath9k: fix crash with WEP in ad-hoc mode

Commit eed8e22f0133e8278b1f8079fcb452f1f9692f9d added support for using
multicast key lookup to support per-vif/sta keys for AP and ad-hoc.
Unfortunately, it also introduced a crash in ad-hoc mode when the sta
pointer is NULL, which happens when setting up an interface with WEP
keys. This patch fixes it by falling back to the assigned key index.
