qcacld-3.0: eSmeCommandDelStaSession stuck in smeCmdActiveList

Browse Source 
qcacld-2.0 to qcacld-3.0 propagation.

1.Use iw tool to let dut connect to remote ap, dut is working
on wlan0.
2.At same time, use hostapd to start sap also on interface
wlan0.

In item1, before connect to ap, dut will do an internal scan
to search ap, if scan result matched configured ap profile,
dut trys to connect to ap.

In item2, when starting sap, found it's sta mode it will try
to disconnect dut with remote ap and close sta session.

  #1 If ap start action happened in item1's scan period, trying
  disconnecting won't take effect as currently sta has not yet
  connected with remote ap.
  So after item1's scan finished, dut continues to do connection.

  #2 During closing sta session, sme issued eSmeCommandDelStaSession,
  as currently sta is doing connection, so session is in started
  status, this cause closure failed, so there is no chance to remove
  cmd in smeCmdActiveList.
  While cmd pending in smeCmdActiveList for 120s, driver issued crash.

The solution is in item1 after scan complete to check whether it's
needed to start following connection. If stop action has been issued
during scan period, then don't do the connection.
