wifi: mt76: mt7925: fix CLC command timeout when suspend/resume

When enter suspend/resume while in a connected state, the upper layer
will trigger disconnection before entering suspend, and at the same time,
it will trigger regd_notifier() and update CLC, causing the CLC event to
not be received due to suspend, resulting in a command timeout.

Therefore, the update of CLC is postponed until resume, to ensure data
consistency and avoid the occurrence of command timeout.
