The memory bank addresses used for these are independent, can (and must) enable both. Also looks like no need to shrink these if FDCAN2 is added, the Reference Manual is a bit unclear but looks like the peripheral's RAM multiplies out for each additional controller.

Summary
This fix was split out from #15989.
Without this fix, extended CAN ID filtering doesn't work on STM32G4. The memory bank addresses used for these are independent, can (and must) enable both.
Also looks like no need to halve these if FDCAN2 is added (as per comment). The Reference Manual is a bit unclear but looks like the peripheral's RAM multiplies out for each additional controller.
