wifi: mt76: mt7921: avoid undesired changes of the preset regulatory domain

Browse Source 
Some countries have strict RF restrictions where changing the regulatory
domain dynamically based on the connected AP is not acceptable.
This patch disables Beacon country IE hinting when a valid country code
is set from usersland (e.g., by system using iw or CRDA).
