ath9k: Fix tx throughput drops for AR9003 chips with AES encryption

commit 4f6760b01bda625e9555e16d8e9ba8126a9c9498 upstream.

While sending aggregated frames in AES, the AR5416 chips
required additional padding b/w subframes. This workaround
is not needed for edma (AR9003 family) chips. With this patch
~4Mbps thoughput improvement was observed in clear environment.
