qcacld-3.0: Fix ref leak for temp sta info node

hdd_is_connection_in_progress_iterator loops through all adapters
and the sta_info present in each adapter to find out
if any connection is in progress. In SAP case, there could be
multiple sta_info present and need to traverse through them by
avoiding running into loop on the same sta_info/released
sta_info. The hdd_for_each_sta_ref_safe helps for the same but
takes two references, one for sta_info and one for a
temporary entry. Release both after checking the
connection status.
