Bluetooth: Use hci_conn_num() for checking number of LE connections
When checking for the current number of LE connections, use hci_conn_num() function instead of a full blown lookup within the connection hash or direct access of the counters. In the case of re-enabling advertising, it is more useful to check for any connection attempt or existing connection.
