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

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

[Deren Wu]

From: Ming Yen Hsieh <mingyen.hsieh@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.

BTW the fixes tag didn't use correct title and I fixed it during commit.
