stm32/fdcan: Fix extended CAN ID filtering for stm32g4.
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.
