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.
