You don't have a license to the PS3 version anymore if you upgraded to the PS4, even if you have a active sub for the game it will only allow you to play on the PS4 unless you buy another copy of the PS3 version then it will allow you to play on both systems cause it the serial number that allows you to play not the actual game data.

Nope you the sub you paid is still valid but can only play on the PS4 since that the serial number you have now.

Unfortunatelly the upgrade process is irreversible so the only option would be to get another copy of PS3 version of the game (those are dirt cheap right now boxed £4 - £5 in UK) and register it to the same SE service account. This will give you "back" all your characters and progress and as a "bonus" also another 30 days of subscription.
