wifi: mt76: mt792x: fix wifi init fail by setting MCU_RUNNING after CLC load

Browse Source 
Set the MT76_STATE_MCU_RUNNING bit only after mt7921_load_clc()
has successfully completed. Previously, the MCU_RUNNING state
was set before loading CLC, which could cause conflict between
chip mcu_init retry and mac_reset flow, result in chip init fail
and chip abnormal status. By moving the state set after CLC load,
firmware initialization becomes robust and resolves init fail issue.
