cld: sme: fix data transmission on disconnect indication
The earlier commit "cld: Stop data transmission prior to disconnect
request" fixed system hang issue when the user is initiating
disconnect. But it has to be fixed when AP is initiating disconnect
and the station is pushing uplink traffic heavily. Once SME receives
deauth/disassoc indication, it is proceeding to roam or post SME
command to disconnect without stopping data transmission. Under
heavy uplink udp traffic, due to the latency in MC thread processing,
all this data is causing the AP to repeatedly exchanging deauth
frame with reason code 7 (Class 3 frame received from nonassociated
station) and causing system hang.
