Sujith Manoharan 176f0e841e ath9k: Fix RX DMA mapping 
After the commit "ath9k: improve dma map failure handling", the
wrong buffer was DMA-unmapped, introducing warnings like the one below.
This patch fixes the issue.

WARNING: at /home/sujith/dev/wireless-testing/lib/dma-debug.c:986 check_sync+0x4bc/0x580()
Hardware name: LIFEBOOK AH531
