ath10k: restore tx sk_buff of htt header for SDIO
ieee80211_report_used_skb of mac80211 use the frame_control of
ieee80211_hdr in sk_buff and indicate it to another function
ieee80211_mgd_conn_tx_status, then it queue work ieee80211_sta_work,
but ieee80211_is_auth(fc) in ieee80211_sta_work check fail when the
authentication has transmitted by ath10k.
When the ath10k report it with HTT_TX_COMPL_STATE_DISCARD, it will be
set without flag IEEE80211_TX_STAT_ACK, then mac80211 should try the
next authentication immeditely, but in fact mac80211 wait 1 second for
it, the reason is ieee80211_is_auth(fc) in ieee80211_sta_work check
fail for the sk_buff which is not restored, the data of sk_buff is not
the begin of ieee80211_hdr, in fact it is the begin of htt_cmd_hdr.
dmesg without this patch, it wait 1 second for the next retry when
ath10k report without IEEE80211_TX_STAT_ACK for authentication:
[ 6973.883116] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 1/3)
[ 6974.705471] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 2/3)
[ 6975.712962] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 3/3)
Restore the sk_buff make mac8011 retry the next authentication
immeditely which meet logic of mac80211.
dmesg with this patch, it retry the next immeditely when ath10k
report without IEEE80211_TX_STAT_ACK for authentication:
[ 216.734813] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 1/3)
[ 216.739914] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 2/3)
[ 216.745874] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 3/3)
