qcacld: Ignore unexpected frames to smooth rssi
Since it receives the beacon/probe resp whose DS param channel
does not match with the RX BD channel, and it can't find the
pBssDescr in the list of pMac->lim.gLimCachedScanHashTable[index]
at the beginning of new scaning round. It adds this new pBssDescr
to the list with wrong rssi value and causes the rssi jumping.
To mitigate this issue, drop these unexpected frames reveived
before one pBssDescr is added.
