[PATCH v3 2/3][SRU][OEM-5.17] UBUNTU: SAUCE: mt76: mt7921: not support beacon offload disable command

[Chris Chiu]

From: Deren Wu <deren.wu at mediatek.com>

BugLink: https://bugs.launchpad.net/bugs/1979173

Beacon disable flow would be handled in bss stop handler automatically.
Force return -EOPNOTSUPP in disable case.
