Remove useless network path of the wifi interface when removing networksubmit/tizen_6.0/20210105.073751accepted/tizen/6.0/unified/20210107.080326

When removing a network, if the network path of the interface is not NULL
and has the same information as the network to be removed, it need to be removed.

Otherwise, when a connection to the same network is attempted later,
the connection may not work normally.
