Subject: [PATCH] net/ncsi: clear Tx enable mode when handling a Config required AEN

Clear the channel Tx enable flag before reconfiguring the channel
when handling a Configuration Required AEN. To avoid misjudging that
the channel Tx has been enabled, which results in the Enable Channel
Network Tx command not being sent during channel reconfiguration.
