This caused a regression when using WEP-LEAP. This patch fixes the regression by keeping track of which key indexes refer to CCMP keys and only using the key miss indication for those.

ath9k_hw: fix interpretation of the rx KeyMiss flag

This commit used the rx key miss indication to detect packets that were
passed from the hardware without being decrypted, however it seems that
this bit is not only undefined in the static WEP case, but also for
dynamically allocated WEP keys. This caused a regression when using
WEP-LEAP.

This patch fixes the regression by keeping track of which key indexes
refer to CCMP keys and only using the key miss indication for those.

However, the clearing of a separate MIC entry with hardware revisions that use combined MIC key layout did not do that with one of the registers. Add the matching register write to the following register to make the KEY4 register write actually complete. This is mostly a fix for a theoretical issue since the incorrect entry that could potentially be left behind in the key cache would not match with received frames.
