qcacld-3.0: Abort ongoing STA connection when SAP goes down

Browse source 
Currently, ongoing STA connection is not aborted when a
stop_adapter is received on SAP. This results in a peer leak in
the below scenario,
1. Turn on SAP.
2. Initiate STA connection to an SSID which has multiple BSSIDs in
   dense environment. Connection gets retried to next BSSID when
   it fails to connect to the current BSSID.
3. Turn off SAP while connection is happening. stop_bss command
   doesn't get processed and waits in queue as the STA connection
   is going on.
4. If stop_bss timer(10 seconds) expires while STA connection is
   in progress, SAP vdev is destroyed without cleaning up self
   peer. So, there would be a peer leak.

Abort the ongoing sta when SAP goes down, so that stop_bss gets
processed cleanly and self peer is also cleaned up.
Same is applicable for P2P_GO as well.
