ath9k: Fix bug in paprd
It is possbile that the transmission of paprd test frame might not get completed in 100ms if tx is stuck. Freeing this skb upon timeout in ath_paprd_calibrate() will result in accessing already freed memory when the associated pending buffer is drained in txq. This patch fixes this issue.
