      ath9k: Fix possible double free of PAPRD skb's · 9cf04dcc
      Mohammed Shafi Shajakhan authored
      
      
      This patch reverts the following commit
      ath9k: remove bfs_paprd_timestamp from struct ath_buf_state
      
      Under high interference/noisy environment conditions where PAPRD frames
      fails heavily introduces a possibility of double freeing skb's and causes
      kernel panic after some time.This patch reverts back to the original approach
      of using paprd_timestamp before freeing the PAPRD frame skb's
