mac80211: fix TX status cookie in HW offload case
When the off-channel TX is done with remain-on-channel offloaded to hardware, the reported cookie is wrong as in that case we shouldn't use the SKB as the cookie but need to instead use the corresponding r-o-c cookie (XOR'ed with 2 to prevent API mismatches). Fix this by keeping track of the hw_roc_skb pointer just for the status processing and use the correct cookie to report in this case. We can't use the hw_roc_skb pointer itself because it is NULL'ed when the frame is transmitted to prevent it being used twice. This fixes a bug where the P2P state machine in the supplicant gets stuck because it never gets a correct result for its transmitted frame.
