* __schBeaconProcessNoSession
*
* FUNCTION:
* Process the received beacon frame when
* -- Station is not scanning
* -- No corresponding session is found
*
* LOGIC:
* Following scenarios exist when Session Does not exist:
* * IBSS Beacons, when IBSS session already exists with same SSID,
* but from STA which has not yet joined and has a different BSSID.
* - invoke limHandleIBSScoalescing with the session context of existing IBSS session.
*
* * IBSS Beacons when IBSS session does not exist, only Infra or BT-AMP session exists,
* then save the beacon in the scan results and throw it away.
*
* * Infra Beacons
* - beacons received when no session active
* should not come here, it should be handled as part of scanning,
* else they should not be getting received, should update scan results and drop it if that happens.
* - beacons received when IBSS session active:
* update scan results and drop it.
* - beacons received when Infra session(STA) is active:
* update scan results and drop it
* - beacons received when BT-STA session is active:
* update scan results and drop it.
* - beacons received when Infra/BT-STA or Infra/IBSS is active.
* update scan results and drop it.
