[PATCH Review V2 1/1] drm/amdgpu: Fix eeprom max record count

[Yang, Stanley]

[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.

Regards,
Stanley
