    net/ncsi: clear Tx enable mode when handling a Config required AEN
    
    [ Upstream commit 6f75cd166a5a3c0bc50441faa8b8304f60522fdd ]
    
    ncsi_channel_is_tx() determines whether a given channel should be
    used for Tx or not. However, when reconfiguring the channel by
    handling a Configuration Required AEN, there is a misjudgment that
    the channel Tx has already been enabled, which results in the Enable
    Channel Network Tx command not being sent.
    
    Clear the channel Tx enable flag before reconfiguring the channel to
    avoid the misjudgment.
