[AMD Official Use Only - AMD Internal Distribution Only]
Only set eeprom table version in the beginning of amdgpu_ras_recovery_init is not enough, because the table version value is set to zero read from device eeprom table in function amdgpu_ras_eeprom_init due to no available eeprom info in a new device that have never loaded driver before.

Stanley
