[next v2] wifi: mt76: mt7921: fix 6GHz disabled by the missing default CLC config

[Deren Wu]

From: Ming Yen Hsieh <mingyen.hsieh at mediatek.com>

No matter CLC is enabled or disabled, the driver should initialize
the default value 0xff for channel configuration of CLC. Otherwise,
the zero value would disable channels.
