qcacld-3.0: Restore deleted connection with total con count <= max count

Currently, deleted connections are not restored if current connection count
is geater than or equal to max no of allowed connection - no of deleted
connection which may cause issue when there are 4 connections and 2 ML sta
link got deleted temporarily for getting pcl list. As max no of connection
allowed are 4, deleted sta links should be restored. In check to restore
the deleted link comparison is done with < max no connection, so deleted
connections are not restored.

Fix is to add a check that current connection count + deleted connection
count should be less than or equal to MAX_NUMBER_OF_CONC_CONNECTIONS.
